Refraction and Reflection Review PPMS

A material with a curved surface that bends light is called a

• o reflection

• o prism

• o medium

• o lens

What can happen when a wave strikes a barrier? Check all that apply

• o it can go through the barrier

• o it can be reflected.

• o it can be absorbed

• o it can be refracted.

You can see your face when you look in a mirror because

• o the surface reflects light waves evenly

• o the surface absorbs light waves that strike it.

What is refraction?

• o the absorbing of a wave as it moves from one medium to another

• o the bouncing of a wave as it moves from one medium to another

• o the bending of a wave as it moves from one medium to another

• o the absorbing of a wave as it strikes a barrier

A distant airplane can be seen on radar because the radar waves

• o are changed to light waves when they hit an airplane, so they are visible.

• o strike an airplane, and are scattered.

• o strike an airplane, and are refracted back to the radar antenna.

• o strike an airplane, and are reflected back to the radar antenna.
