Question

Describe the effects lenses have on light and their possible technological applications.

Answer 1

Step-by-step explanation:

Lenses are made of glass or other transparent materials for light. They are optically dense so light slows down on entering it. It is called refraction which bends the light on entering and leaving the lenses.

Refraction by lenses can be used for all kinds of optical applications, e.g. camera, telescope, magnifying glasses, solar heating.

Answer 2

lenses is used to refract light inward or outward

there are two type of lenses. Concave and convex lense

Convex lense converge ray of light

Concave lense diverge ray of light

useful application =:

=> camera

=> flashlight

=> lasers

=> Binoculars and Telescope
