L1 and L2 Review

A material in which a wave travels

• Base

• Vacuum

• Medium

• Current

The relationship between amplitude and energy can be described as..

• Directly proportional (increase and decrease together)

• Inversely proportional (when one increases, the other decreases)

The relationship between frequency and wavelength can be described..

• Directly proportional (increase and decrease together)

• Inversely proportional (when one increases, the other decreases)

Humans can hear frequencies as low as 21 Hz. If the sound is measured during 3 seconds, how many wavelengths pass?

• 7

• 24

• 63

• 18

What change could explain the difference between the waves?

• The speed of the wave increased.

• The source of vibrations increased the speed of vibrations.

• The wavelength of the wave increased.

• The energy provided by the source of vibrations increased.

Which statement correctly describes the relationship between wavelength and frequency?

• As wavelength decreases, frequency increases because more waves pass a point each second.

• As wavelength decreases, frequency increases because fewer waves pass a point each second.

• As wavelength increases, frequency increases because more waves pass a point each second.

• As wavelength increases, frequency increases because fewer waves pass a point each second.

A sound wave takes about 5 seconds to move through a material that is 10 meters long. How many meters per second is this?

• 0.5 m/s

• 5 m/s

• 0.2 m/s

• 2 m/s

Kevin gathers amplitude and energy data for four ocean waves, as shown in the table. Which equation best represents the relationship between the amplitude (A) of an ocean wave and its energy (E), according to the data in the table?

• E = A

• E = A²

• 1/E = A

• 1/E = A²

In a transverse wave, the particle motion is _________________________ to the movement of the wave.

• Perpendicular

• Parallel

In a longitudinal wave, the particle motion is ________________________ to the movement of the wave.

• Perpendicular

• Parallel
