A guitar string is plucked. What best describes the formation and transmission of the sound wave?

The string vibrates the surrounding air, which produces a transverse wave.

The string vibrates the surrounding air, which produces a longitudinal wave.

The string produces a longitudinal wave that travels without a medium.

The string produces a transverse wave that travels without a medium.

person A

person B

person C

person D

0 Hz

The diagrams show the sound waves produced in one second from various tuning forks.Which sound wave has the lowest pitch?

An illustration of a tuning fork with lines parallel to the fork moving out. The lines start out farther apart, get closer together and then farther apart again.

An illustration of a tuning fork with lines parallel to the fork moving out. The lines start out close together, get farther apart and then close together again. The line pattern then repeats. The farther apart section gets wider the further the lines are from the fork.

Which best explains why sound travels fastest through a solid?

Sound is a mechanical wave, so closer molecules in the medium cause energy to transfer faster.

Sound is a mechanical wave, so if the volume of the medium is greater, more energy is transferred.

Sound is an electromagnetic wave, so the medium does not affect the speed.

Sound is an electromagnetic wave, so a greater amplitude results in a greater speed.

Juan is standing on the street. An ambulance moves toward him and then passes by.

The pitch remains constant as the ambulance moves toward and then away from Juan.

The pitch increases and decreases in a repeated pattern as the ambulance passes Juan.

The pitch drops to a lower pitch once the ambulance passes by Juan.

The pitch increases to a higher pitch once the ambulance passes by Juan.

Sound will travel slowest through which medium?

water at 55°C

water at 75°C

ice at 0°C

ice at –25°C

What is the name of the perceived change in a sound wave’s frequency due to motion between the observer and the sound source?

diffraction

Doppler effect

reflection

resonance
