A diverging lens (A) is one that spreads rays of light. Also known as a concave lens, it is thinner at the center than at the edges. When parallel rays of light pass through a diverging lens, they are refracted and diverge away from a focal point on the same side as the object. Unlike a converging lens, which forms a real image where light rays converge, a diverging lens forms a virtual image. This virtual image appears to be located on the same side of the lens as the object, and it cannot be projected onto a screen. Instead, the light rays appear to diverge from the virtual image point, giving the impression of an image that is smaller and upright compared to the object. Diverging lenses are used in various optical devices, such as eyeglasses for correcting nearsightedness (myopia), where the lens helps to spread out light rays before they enter the eye, allowing for clearer vision by adjusting how light converges within the eye.
A converging lens (B) is one that collects rays of light. Also known as a convex lens, it is thicker at the center than at the edges. When parallel rays of light pass through a converging lens, they are refracted and converge to a focal point on the opposite side of the lens. This focal point is wheRead more
A converging lens (B) is one that collects rays of light. Also known as a convex lens, it is thicker at the center than at the edges. When parallel rays of light pass through a converging lens, they are refracted and converge to a focal point on the opposite side of the lens. This focal point is where the lens forms a real or virtual image, depending on the location of the object relative to the focal point and the lens. A real image is formed when light rays actually converge at a point and can be projected onto a screen, whereas a virtual image appears to be located at the focal point but cannot be projected. The ability of a converging lens to collect and focus light rays makes it useful in applications such as cameras, magnifying glasses, and corrective lenses for vision correction, where forming clear images or focusing light is essential.
When a person stands between two plane mirrors inclined at a 60° angle, they will see five images of themselves (C). The angle of 60° between the mirrors facilitates the creation of multiple reflections. The person's image is reflected in the first mirror and then reflected again in the second mirroRead more
When a person stands between two plane mirrors inclined at a 60° angle, they will see five images of themselves (C). The angle of 60° between the mirrors facilitates the creation of multiple reflections. The person’s image is reflected in the first mirror and then reflected again in the second mirror. This process continues, with each mirror reflecting the image formed by the other mirror. Specifically, the person sees their original image, two additional images from the first set of reflections (totaling three images), and then two more images from the second set of reflections (totaling five images). This symmetrical arrangement and the reflective properties of the mirrors lead to the formation of multiple distinct images of the person, illustrating the principle of multiple reflections in an angled mirror configuration. Adjusting the angle between mirrors affects the number and positioning of these images, demonstrating the dynamic interaction of light in reflective environments.
When two plane mirrors are placed at a 90° angle, an infinite number of images of the candle will be formed [D]. This occurs because each mirror reflects the image of the candle from the other mirror, resulting in a cascade of reflections that continue indefinitely. The initial image of the candle iRead more
When two plane mirrors are placed at a 90° angle, an infinite number of images of the candle will be formed [D]. This occurs because each mirror reflects the image of the candle from the other mirror, resulting in a cascade of reflections that continue indefinitely. The initial image of the candle is reflected in one mirror and then reflected again in the perpendicular mirror, creating a second image. Each subsequent reflection generates additional images, with the number of images increasing without limit due to the continuous and symmetrical reflection pattern between the mirrors. This phenomenon illustrates the principle of multiple reflections in perpendicular mirror setups, where the angle between the mirrors facilitates the creation of an infinite array of images. The concept underscores the geometric and optical properties involved in the formation of images in mirror systems, demonstrating the complexity and richness of light reflection in a controlled environment.

When an object is placed between two parallel plane mirrors, an infinite number of images are formed (D). This phenomenon occurs because each mirror reflects the image formed by the other mirror, creating an endless sequence of reflected images. The process begins with the object’s initial reflection in one mirror, which is then reflected in the opposite mirror, and so on. Each reflection produces a new image that is slightly displaced from the previous one, leading to an infinite series of images that extend indefinitely along the axis between the mirrors. This scenario demonstrates the principle of multiple reflections between parallel mirrors, where the distance between consecutive images decreases progressively but continues indefinitely. The concept is a fundamental illustration of how light behaves in a reflective environment and underscores the role of geometry and optics in understanding the formation of images in parallel mirror systems.
