Light and Lenses Quiz

This happens when light rays pass through and bend as they travel from one kind of substance to another.

• Dispersion

• Reflection

• Refraction

• Polarization

What type of lens is characterized by thin middle but thicker edges?

• concave

• convex

• plane

• spherical

Which is a CORRECT statement?

• Light rays travel at the same speed from vacuum to air.

• Light rays bounce back and bend as they pass through a lens.

• A higher index of refraction means slower speed of light rays as they travel.

• In lens, the angle of incidence is always greater than the angle of refraction.

A light ray travels from air to glass, which of the following will be most likely to happen?

• The angle of refraction will be higher than the angle of incidence.

• The incident ray will remain its speed as it enters the glass material.

• The incident ray will bend towards the normal line as it moves to glass.

• The ray of light will speed up as it crosses the boundary between the air and glass.

What type of lens is also referred to as converging lens?

• concave

• convex

• plane

• spherical
