Wave Phenomena Quiz (Lesson 2)

What is reflection?

• The bending of waves as they enter a new medium

• The bouncing back of waves when they hit a surface

• The absorption of wave energy

• The spreading of waves around a barrier

According to the Law of Reflection, what is true about the angle of incidence and the angle of reflection?

• They are equal

• The angle of incidence is greater

• The angle of reflection is greater

• They are unrelated

Which of the following is an example of reflection?

• A straw appearing bent in water

• An echo in a canyon

• A rainbow forming in the sky

• A paper towel soaking up water

What happens to the energy of a wave during reflection?

• It is absorbed

• It is transmitted

• It changes direction but does not lose energy

• It is converted into heat

Which of the following is NOT a reflective surface?

• Mirror

• Water

• Dark asphalt road

• Glass

What is refraction?

• The bouncing back of waves

• The bending of waves as they enter a new medium

• The spreading of waves around a barrier

• The absorption of wave energy

Why does refraction occur?

• Because waves change speed when entering a new medium

• Because waves bounce off surfaces

• Because waves lose energy

• Because waves spread out

What happens to light when it passes from air into water?

• It speeds up and bends away from the normal

• It slows down and bends toward the normal

• It continues in a straight line

• It is absorbed

Which of the following is an example of refraction?

• A mirror reflecting light

• A straw appearing bent in water

• An echo in a canyon

• A paper towel soaking up water

What causes a rainbow to form?

• Reflection

• Refraction

• Diffraction

• Absorption
