Wave Properties

What can be refracted? Choose the best answer.

• Light

• Sound

• Heat

• Anything that travels in waves

Blue light bends more than red light when it passes through glass. Thus, blue light has a greater:

• Angle of refraction

• Wave speed

• Amount of diffraction in glass

• Amplitude

What is the main difference between refraction and diffraction?

• Refraction is a phenomenon that affects light; diffraction is a phenomenon that affects sound.

• Refraction involves the bending of light; diffraction involves the bending and spreading of light, usually around an obstacle.

• Refraction usually happens in the atmosphere; diffraction usually happens closer to the earth's surface.

• Refraction involves changes to the density of light; diffraction involves changes to the speed of light.

A wave of constant wavelength diffracts as it passes through an opening in a barrier. As the size of the opening is increased, the diffraction effects

• decrease

• increase

• remain the same

This image is representing what wave interaction?

• Refraction
• Diffraction

What happens to the frequency of a wave as it passes through a gap？

• Increases

• Decreases

• No change

• None of above

Which diagram best represents the shape and direction of a series of wave fronts after they have passed through a small opening in a barrier?

• 
• 
• 
• 

Which form of Interference is occurring in this picture?

• Reflection
• Refraction
• Diffraction

Which best defines reflection?

• The bouncing of a wave off a boundary or object

• The bending of a wave as it enters a new medium

• The spreading of a wave around boundaries or objects

• The overlapping of waves

If the man throws the spear at the image, then he will miss the fish. This is because the water bends the light. What is this an example of?

• Reflection

• Refraction

• Diffraction
