Exp 1 Characteristics of Waves Quiz Retake Review

What does amplitude measure in a wave, and what does wavelength measure?

• Amplitude measures wave speed; wavelength measures wave energy.

• Amplitude measures wave height; wavelength measures the distance between two similar points on the wave.

• Amplitude measures wave frequency; wavelength measures how quickly the wave travels.

• Amplitude and wavelength both measure wave height.

How might two waves differ if one has a shorter wavelength but the same amplitude as the other?

• The wave with a shorter wavelength has more energy.

• The wave with a shorter wavelength will have a higher frequency.

• The wave with a shorter wavelength will move slower.

• The wave with a shorter wavelength will look the same but sound different.

magine two waves traveling at the same speed. If one has a higher frequency, what can you infer about its wavelength?

• It will have a shorter wavelength

• It will have a longer wavelength

• Its wavelength will stay the same

• Its amplitude will be higher

What effect does a higher amplitude have on the energy of a wave?

• it decreases the wave's energy

• it increases the wave's energy

• It has no effect on energy

• it slows the wave down

If two waves have the same wavelength but different amplitudes, how might they appear or behave differently in light or sound?

• the wave with a lower amplitude will sound louder

• the wave with a higher amplitude will be quieter or dimmer

• the wave with a higher amplitude will appear brighter or sound louder

• both waves will appear or sound the same

ou observe two sound waves of equal frequency, but one sounds louder than the other. What can you conclude about the amplitudes of these waves?

• the louder wave has a higher amplitude

• the louder wave has a lower amplitude

• both waves have equal amplitude

• the quieter wave has a higher amplitude

What is the difference between a wave that moves in a side-to-side motion and one that moves in an up-and-down motion? There are 2 correct answers.

• Side-to-side motion is typical of S-waves; up-and-down motion is typical of P-waves.

• Side-to-side motion is typical of surface waves; up-and-down motion is typical of transverse waves.

• Side-to-side motion is typical of longitudinal waves; up-and-down motion is typical of transverse waves.

• • Side-to-side motion is typical of P-waves; up-and-down motion is typical of S-waves.

How do S-waves and P-waves affect the ground differently as they travel through the Earth?

• S-waves create more horizontal motion, and P-waves create vertical motion.

• S-waves create more vertical motion, and P-waves create compression and expansion.

• P-waves create only horizontal motion, and S-waves create compression.

• S-waves cause shaking, while P-waves do not cause any ground motion.

If you were to design a building to withstand ground movement, how might you design it to resist transverse wave motion?

• make the building shorter and wider

• use materials that can absorb compression

• use rolling supports to absorb up and down movement

• use solid rock foundations to block waves

How are wavelength and frequency related if the speed of the wave remains the same?

• as frequency increases, wavelength increases.

• as frequency increases, wavelength decreases.

• frequency and wavelength are not related.

• both frequency and wavelength remain the same.
