Quiz 4

A student knows that microwaves have more energy than radio waves. The student studies the diagram shown below, which models wavelengths in the electromagnetic spectrum.

Based only on this information, which conclusion can the student make about electromagnetic waves and energy?

• The greater the distance an electromagnetic wave travels, the lower its energy.

• The greater an electromagnetic wave's wavelength, the lower its energy.

• The larger an electromagnetic wave's amplitude, the lower its energy.

• The longer an electromagnetic wave lasts, the lower its energy.

Eugene recorded the sound waves made by his drum on an oscilloscope. He found that if he hit his drum harder, the amplitude of the waves got larger. How did the sound from his drum change?

• The sound became louder in volume.

• The sound became softer in volume.

• The sound became higher in pitch.

• The sound became lower in pitch.

How does the wavelength of the echolocation in dolphins differ from the wavelength of echolocation in bats?

• The wavelength of dolphin echolocation is longer than the wavelength of bat echolocation.

• The wavelength of dolphin echolocation is shorter than the wavelength of bat echolocation.

• The wavelength of dolphin echolocation is the same as the wavelength of bat echolocation.

• The wavelength of dolphin echolocation is twice as short as the wavelength of bat echolocation.

How are wavelength and frequency related?

• If the distance between the crests of the waves increase, the frequency decreases.

• If the distance between the crests of the waves decrease, the frequency decreases.

• If the speed between the crests of the waves increases, the frequency increases.

• If the speed between the crests of the waves decreases, the frequency increases.

When the wavelength of a wave increases, what happens to the frequency of the wave?

• The frequency increases.

• The frequency decreases.

• The frequency gets louder.

• The frequency remains the same.

• It increases.

• It decreases.

• It depends on resonance.

As a wave approaches the shore, the bottom of the wave begins to drag on the floor of  the ocean. How does this affect the wavelength and wave height of a wave?

• The wave height increases, and the wavelength does not change.

• The wave height decreases, and the wavelength also decreases

• The wave height does not change, but the wavelength increases.

• The wave height increases, and the wavelength decreases.

On a guitar, the longest string vibrates slowly, and the shortest string vibrates very quickly. What conclusion can be made about the sound that each string makes?

• The long string makes a loud sound and the short string makes a soft sound, because things that are longer make louder sounds.

• The long string makes a soft sound and the short string makes a loud sound, because things that are longer make softer sounds.

• The long string makes a high-pitched sound and the short string makes a low-pitched sound, because things that vibrate slowly have a higher pitch.

• The long string makes a low-pitched sound and the short string makes a high-pitched sound, because things that vibrate slowly have a lower pitch.

Which of the following statements best describes the relationship between wavelength and frequency?

• The longer the wavelength, the higher the frequency.

• The longer the wavelength, the lower the frequency.

• The shorter the wavelength, the lower the frequency.

• The shorter the wavelength, the weaker the frequency.
