Lens and mirrors quick check
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.
