The Energy of Waves

Waves transfer

• matter

• energy

• particles

• water

Which of the following results in more energy in a wave?

• a smaller wavelength

• a lower frequency

• a shallower amplitude

• a lower speed

What is the speed of a wave that has a wavelength of 2 m and a frequency of 6 Hz?

• 3 m/s

• 8 m/s

• 12 m/s

• 24 m/s

What is the frequency of a wave if the wave has a speed of 12 cm/s and a wavelength of 3 cm?

• 4 Hz

• 8 Hz

• 24 Hz

• 36 Hz

A wave has a frequency of 5 Hz and a wave speed of 18 m/s. What is its wavelength?

• 2 m

• 2.4 m

• 3 m

• 3.6 m

The combining of waves as they overlap is known as

• interference

• diffraction

• refraction

• resonance

As the wavelength increases, the frequency

• decreases.

• increases.

• remains the same.

• increases and then decreases.

The wave property that is related to the height of a wave is the

• wavelength.

• amplitude.

• frequency.

• wave speed.

During Constructive interference,

• the amplitude increases.

• the frequency decreases.

• the wave speed increases.

• All of the above.

Refraction occurs when a wave enters a new medium at an angle because

• the frequency changes.

• the amplitude changes.

• the wave speed changes.

• None of the above.
