Physics B - Wave Properties

A frequency generator sends a 550 Hz sound wave through both water and ice. What is the difference in wavelength between the wave produced in ice and the wave produced in water?

3.1 m

An FM radio station broadcasts at 9.23 × 107 Hz. Given that the radio waves travel at 3.00 × 108 m/s, what is the wavelength of these waves?

3.25 m

The speed of sound in ice, water, and steam is shown. What best explains the speed of sound in different states of matter?

Sound travels fastest in ice because energy is easier to transfer when the molecules are close together.

What best describes the speed of light waves in solids, liquids, and gases?

The speed is fastest in gases.

What factors affect the speed of a wave? Check all that apply.

WRONG = X the amplitude of the wave the type of wave the type of medium CORRECT = the temperature of the medium the type of wave the type of medium

Sound travels slowest through what temperature of water?

WRONG = 60°C CORRECT = 20°C

The diagram shows a wave traveling through a medium. Identify point B.

crest

What best describes the relationship between wavelength and frequency in an electromagnetic wave?

inversely proportional

Study the diagram. Point C identifies the _______ of the wave.

trough

On a cold day, the speed of sound in air is 330 m/s. A note with a frequency of 1,320 Hz is played on an instrument. What is the wavelength of that sound wave?

0.25 m
