The color of an opaque object is due to the color which it absorbs (Option A). When light illuminates an opaque object, the object absorbs certain wavelengths of light while reflecting or scattering others. The absorbed wavelengths correspond to the colors that are not seen by the observer, as they are absorbed by the object’s surface material. The wavelengths that are not absorbed are either reflected directly back to the observer or scattered in various directions, depending on the surface texture and material properties of the object. For example, a red object appears red because it absorbs most of the wavelengths of light except for red, which is reflected back to the observer’s eye. This principle governs the perception of color in everyday objects and plays a crucial role in fields such as art, design, and materials science, where understanding light interaction with surfaces helps in creating desired visual effects and appearances.

The color combination most convenient during day and night is yellow and blue (Option C). Yellow is highly visible in daylight due to its wavelength, which stands out against natural backgrounds. Blue, on the other hand, provides good contrast in low-light conditions, such as dusk or nighttime, as it reflects well under artificial lighting and moonlight. Together, yellow and blue offer versatility in visibility across different lighting environments, making them suitable for applications like traffic signs, safety vests, and emergency vehicles. This combination takes advantage of human visual sensitivity to certain wavelengths of light, enhancing visibility and ensuring safety during both day and night. Understanding color combinations for visibility is crucial in fields such as transportation, outdoor safety, and signage design, where effective communication and recognition are essential for public safety and efficient operation.
The color with the maximum wavelength is red (Option D). In the visible light spectrum, red light has the longest wavelength, typically ranging from around 620 to 750 nanometers.

The color with the maximum wavelength is red (Option D). In the visible light spectrum, red light has the longest wavelength, typically ranging from around 620 to 750 nanometers. This longer wavelength means that red light has lower energy and a lower frequency compared to other colors like blue, green, and yellow. Because of its long wavelength, red light refracts or bends the least when passing through mediums such as prisms or water droplets, which is why it appears on the outer edge of a spectrum or rainbow. The long wavelength of red light also contributes to its use in various applications, such as in stop signs and traffic lights, because it can be seen from a distance. Understanding the wavelengths of different colors is essential in fields like optics, astronomy, and photography, as it affects how light interacts with materials and how we perceive color.

The process of separation of white light into its different colors is called dispersion (Option B). Dispersion occurs when light passes through a medium like a prism, causing each wavelength of light to refract, or bend, at different angles. This bending is due to the different refractive indices for different wavelengths of light. For instance, when white light enters a prism, the various colors that constitute white light, such as red, orange, yellow, green, blue, indigo, and violet, bend by different amounts. Violet light, having the shortest wavelength, bends the most, while red light, having the longest wavelength, bends the least. This spreading out of light into its constituent colors results in a spectrum, which is often observed as a rainbow. Dispersion demonstrates the wave nature of light and is crucial in understanding optical phenomena and technologies like spectroscopy, which analyzes the light spectrum to determine the composition of materials.

The three basic colors are blue, red, and green (Option C). These colors are primary in the additive color model, which is used for light sources such as computer screens, televisions, and human vision. In this model, the primary colors combine in various ways to produce other colors. For instance, red and green light mix to produce yellow, green and blue produce cyan, and blue and red produce magenta. When blue, red, and green light are combined in equal intensities, they produce white light. This model is fundamental to technologies that use light to display colors, such as RGB color systems in digital screens. Understanding these primary colors is crucial for fields like digital imaging, color printing, and lighting design, as it helps in accurately reproducing colors and creating a wide range of hues by mixing the basic colors in different proportions.

Primary colors are those colors which cannot be produced by mixing other colors (Option D). They are fundamental in both light and pigment contexts. In the additive color model, used for light, the primary colors are red, green, and blue. These colors combine in various ways to produce other colors, including white light when combined in equal intensities. For example, red and green light mix to produce yellow, green and blue produce cyan, and blue and red produce magenta. In the subtractive color model, used for pigments and dyes, the primary colors are red, yellow, and blue. These colors mix to create other hues, with red and yellow producing orange, yellow and blue producing green, and blue and red producing purple. Understanding primary colors is essential in fields such as art, design, and color science, as they form the foundation for color mixing and the creation of a full spectrum of colors.
When white light passes through a prism, the color which deviates the least is red (Option A). This deviation occurs due to the different wavelengths of light that make up white light.

When white light passes through a prism, the color which deviates the least is red (Option A). This deviation occurs due to the different wavelengths of light that make up white light. Red light has the longest wavelength, around 620-750 nanometers, among the visible spectrum. Because of its longer wavelength, red light experiences a lower refractive index in the prism material compared to colors with shorter wavelengths, such as violet. As a result, red light bends the least when passing through the prism. This principle of dispersion, where light is spread out into its constituent colors, demonstrates that each color refracts at different angles based on its wavelength. In the visible spectrum created by the prism, red light appears at the opposite end of violet, showing the least amount of deviation and appearing on the outer edge of the spectrum.

When white light passes through a prism, the color which deviates the most is violet (Option B). This deviation occurs because different colors of light have different wavelengths and thus bend by different amounts when passing through a medium like a prism. Violet light has the shortest wavelength among visible colors, around 380-450 nanometers. Due to its shorter wavelength, it experiences a higher refractive index in the prism material compared to colors with longer wavelengths, like red. Consequently, violet light refracts, or bends, more sharply than the other colors, resulting in the greatest deviation. This is why violet appears at one end of the spectrum when white light is dispersed by a prism, demonstrating the principle of dispersion where different wavelengths of light spread out to form a continuous spectrum.
White light is made up of a combination of seven colors (Option D). These colors are red, orange, yellow, green, blue, indigo, and violet.

White light is made up of a combination of seven colors (Option D). These colors are red, orange, yellow, green, blue, indigo, and violet. When white light passes through a prism, it undergoes refraction at the prism’s surfaces. Each color in white light has a different wavelength, and due to this, they bend at different angles upon entering and exiting the prism. This bending causes the light to spread out into its constituent colors, creating a spectrum. This process, known as dispersion, was first explained by Sir Isaac Newton, who demonstrated that white light is a mixture of these seven colors. The phenomenon can be observed in nature in the form of rainbows, where sunlight is dispersed by water droplets in the atmosphere, displaying the full spectrum of visible light.
