The three basic colors are blue, red, and green. These colors are primary in the additive color model used for light. They combine in various ways to produce a wide spectrum of colors, including white light when combined in equal ...

The process of separation of white light into its different colors is called dispersion. This phenomenon occurs when light passes through a medium, such as a prism, causing different wavelengths (colors) of light to refract at different angles and spread ...
The color with the maximum wavelength is red. Red light has the longest wavelength among the visible spectrum, typically ranging from approximately 620 to 750 nanometers. This longer wavelength causes red light to refract less sharply than other colors when ...
The color combination most convenient during day and night is yellow and blue. These colors provide high visibility and contrast in various lighting conditions, aiding visibility during both daylight and nighttime.
The color of an opaque object is due to the color which it absorbs. When light strikes an opaque object, certain wavelengths (colors) of light are absorbed by the object’s surface material. The remaining wavelengths are reflected or scattered, giving ...
If a green electric bulb is installed in a room, the red cloth will appear black colored. This is because green light is absorbed by the red cloth, which reflects only red wavelengths. Since green light is absent, the cloth ...
The additional yellow lights on some transport vehicles are used to improve visibility in foggy or hazy conditions. This is because yellow light has a longer wavelength than white light, allowing it to better penetrate through the water droplets in ...
Light can be separated into its constituent colors using a prism. When white light passes through a prism, it undergoes dispersion, where different wavelengths (colors) of light bend by different amounts, creating a spectrum of colors from red to violet.
When red glass is heated at high temperature, it will appear green. This phenomenon occurs due to changes in the glass’s structure at high temperatures, altering its light absorption properties and causing it to transmit green light instead of red.
The color of light is determined by its wavelength. Wavelength corresponds to the distance between successive peaks or troughs of a wave and determines the color perceived by the human eye. Different wavelengths of light correspond to different colors in ...
