Concave and Convex Lenses Review

What is a concave lens?

• A lens that is thicker in the center and thinner at the edges, used to converge light rays.

• A lens that is thinner in the center and thicker at the edges, used to diverge light rays.

• A lens that has a uniform thickness throughout, used to focus light rays.

• A lens that is shaped like a flat surface, used to reflect light rays.

What happens to light rays when they pass through a convex lens?

• Light rays diverge away from each other.

• Light rays converge to a point after passing through a convex lens.

• Light rays are absorbed by the lens material.

• Light rays change color as they pass through the lens.

What does a concave lens do?

• A concave lens makes things smaller.

• A concave lens makes things larger.

• A concave lens has no effect on size.

• A concave lens only focuses light in one direction.

What is reflection?

• Reflection is the bending of light rays as they pass through a medium.

• Reflection is the bouncing back of light rays when they hit a surface.

• Reflection is the absorption of light by a surface.

• Reflection is the scattering of light in different directions.

What is refraction?

• Refraction is the bending of light rays as they pass from one medium to another.

• Refraction is the reflection of light rays off a surface.

• Refraction is the absorption of light by a medium.

• Refraction is the scattering of light in different directions.

What type of lens is a magnifying glass?

• A concave lens

• A convex lens

• A plano-convex lens

What is absorption in terms of light?

• Absorption is when light is taken in by a material and not reflected or transmitted.

• Absorption is when light is bounced off a surface.

• Absorption is when light passes through a material without any interaction.

• Absorption is when light is scattered in different directions.

What is the focal point of a lens?

• The point where light rays converge or appear to diverge from.

• The point where light rays are completely absorbed.

• The point where light rays are reflected back.

• The point where light rays are scattered in all directions.

What is diffusion in the context of light?

• Diffusion is the absorption of light by a surface.

• Diffusion is the reflection of light at a surface.

• Diffusion is the scattering of light rays in many directions.

• Diffusion is the transmission of light through a medium.
