2.

Definition: The spreading out of waves as they pass through an opening or around objects.

a)

Reflection

b)

Refraction

c)

Diffraction

d)

Resonance

3.

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

a)

decrease

b)

increase

c)

remain the same

4.

A wave is diffracted as it passes through an opening in a barrier. The amount of diffraction that the wave undergoes depends on both the

a)

amplitude and frequency of the incident wave

b)

wavelength and speed of the incident wave

c)

wavelength of the incident wave and the size of the opening

d)

amplitude of the incident wave and the size of the opening

5.

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?

a)
b)
c)
d)
6.

Radio waves diffract around buildings more than light waves do because, compared to light waves, radio waves

a)

move faster

b)

move slower

c)

have a higher frequency

d)

have a longer wavelength

7.

Waves pass through a 10-centimeter opening in a barrier without being diffracted. This observation provides evidence that the wavelength of the waves i

a)

much shorter than 10 cm

b)

equal to 10 cm

c)

longer than 10 cm but shorter than 20 cm

d)

longer than 20 cm

8.

how does diffraction work

a)

it goes through water and air

b)

is a beam of light stopping at a wall

c)

it bounces off of light

d)

is the bending of light as it passes around the edge of an object

9.

a)
increases
b)
decreases
c)
stays the same
10.
