The part of the eye that controls the amount of light entering the eye is the iris. The iris adjusts the size of the pupil, regulating the light that reaches the retina, thereby ensuring optimal lighting conditions for vision in ...

The power of a convex lens with a focal length of 0.2 meters will be +5D. Power (in diopters) of a lens is calculated as the reciprocal of its focal length in meters, so a focal length of 0.2 meters ...
The mirror used for shaving is a plane mirror. It provides a non-inverted virtual image that appears to be the same size as the object, making it suitable for tasks requiring accurate reflection without distortion.
A converging lens is one that collects rays of light. It is thicker at the center than at the edges, causing parallel rays of light passing through it to converge at a focal point beyond the lens, where a real ...
The nature of light radiation is similar to both wave and particle. This dual nature, known as wave-particle duality, is a fundamental concept in quantum mechanics, showing that light exhibits wave-like properties such as interference and diffraction, and particle-like properties ...
