Lens and mirrors quick check

Answer 1

1. What is the main difference between a lens and a mirror?

A lens is a piece of transparent material that refracts light to converge or diverge it, while a mirror is a smooth surface that reflects light.

2. How does a concave lens differ from a convex lens?

A concave lens is thinner at the center than at the edges and causes light rays to diverge, while a convex lens is thicker at the center and causes light rays to converge.

3. What type of mirror can produce a real and inverted image?

A concave mirror can produce a real and inverted image.

4. What type of lens is used for correcting nearsightedness?

A concave lens is used for correcting nearsightedness by diverging the light rays entering the eye.

5. How does a mirror reflect light differently from a lens?

A mirror reflects light by bouncing it off the surface at an angle equal to the angle of incidence, while a lens refracts light by bending it as it passes through the material.
