Using Sound — Unit test

Question 1

Which statement can be made about the amplitude of any transverse wave?

Revolt · Accepted Answer

It is the length from the midpoint to the crest.

Question 2

Yolanda is studying two waves. The first wave has an amplitude of 2 m, and the second has an amplitude of 3 m.

Revolt · Accepted Answer

She can use constructive interference to generate a wave with an amplitude of 3.5 m.

Question 3

A 2-column table with 4 rows. The first column labeled wave has entries W, X, Y, Z. The second column labeled Observations has entries its motion is perpendicular to wave motion, its particles move up and down, its particles only move small amounts, its motion is parallel to wave motion.

Revolt · Accepted Answer

Waves W and X are transverse waves, Wave Y could be a longitudinal or transverse wave, and Wave Z is a longitudinal wave.

Question 4

As the temperature of a medium increases, the speed of the sound wave

Revolt · Accepted Answer

increases because the particles bump into each other more often.

Question 5

What is common between transverse waves and longitudinal waves?

Revolt · Accepted Answer

Both move faster at higher temperatures

Question 6

Which waves can travel through space?

Revolt · Accepted Answer

electromagnetic waves only

Question 7

Which do sound waves travel fastest through?

Revolt · Accepted Answer

solids

Question 8

Which situation would result in interference?

Revolt · Accepted Answer

a wave increasing in energy as it hits another wave

Question 9

Which feature of a wave can be calculated using the formula below?number of wavelengths / time

Revolt · Accepted Answer

frequency

Question 10

Which best describes what happens if two waves meet and build on each other?

Revolt · Accepted Answer

constructive interference
