Behavior of Waves Quiz

What causes an echo?

• The reflection of sound waves

• The refraction of light waves

• The interference of water waves

• The diffraction of radio waves

What is the law of reflection?

• The angle of incidence is equal to the angle of reflection

• The angle of incidence is greater than the angle of reflection

• The angle of incidence is less than the angle of reflection

• The angle of incidence has no relation to the angle of reflection

What causes a pencil to appear broken in water?

• Refraction of light waves

• Reflection of sound waves

• Interference of water waves

• Diffraction of radio waves

What is diffraction?

• The bending of a wave caused by a change in its speed

• The bending of a wave around a barrier

• The point where two waves meet and overlap

• The vibration of an object at its natural frequencies

What happens during constructive interference?

• Waves cancel each other out

• Waves add together to form a larger wave

• Waves change direction and bend

• Waves vibrate between nodes

What is a standing wave?

• A wave pattern that forms when two waves cancel each other out

• A wave pattern that forms when two waves add together

• A wave pattern that forms when two waves change direction

• A wave pattern that forms when two waves vibrate in opposite directions

What is resonance?

• The bending of a wave around an object

• The vibration of an object at its natural frequencies

• The point where two waves meet and overlap

• The absorption of energy by an object

What can cause an object to break apart due to resonance?

• Constructive interference

• Destructive interference

• Diffraction

• Absorption of energy

What causes a bell to make different sounds?

• The bending of light waves

• The interference of sound waves

• The vibration at natural frequencies

• The absorption of energy

What type of waves can diffract the most?

• Sound waves

• Light waves

• Water waves

• Radio waves
