During a nervous moment of the game, Coach Chowder paced back and forth along the sidelines from the 25.0-yard line to the 35.0-yard line. The coach made exactly 5 back and forth cycles in 2.00 minutes.
What was the frequency (in Hz) of Coach Chowder's pacing?
What is 0.0417 Hz
300
True or false: the observed frequency of a wave is dependent on how close you are to the wave, according to the doppler effect.
What is true
300
A tuning fork produced 5-Hz beat frequency when played with a second 316-Hz tuning fork. What are the two possible frequencies of the first tuning fork?
What is 311 Hz and 321 Hz
400
The part of the wave labeled E
What is wavelength
400
What the motion of a longitudinal wave is like.
What is "back and forth"
400
A wire vibrates at 7.17 Hz to produce transverse waves having a wavelength of 45.7 cm. Determine the speed (in m/s) of the transverse waves.
What is 3.28 m/s
400
True or false: Sound waves need a medium to travel through.
What is true

Herds of African elephants are generally spread over large areas. Infrasonic sound waves (sound waves below the human range of frequency detection) are used by these elephants to locate each other and to communicate. Sound waves with low frequencies have a greater ability to bend around obstacles and generally carry further. Scientists have detected sound waves with frequencies as low as 13 Hz being produced by elephants. Assuming a speed of sound of 344 m/s, determine the wavelength of these sound waves.
What is 26.46 m
500
How tall or the height of a wave is described as...
What is amplitude
500
The difference between constructive and destructive interference.
What is constructive interference typically results in a larger amplitude while destructive interference results in a smaller amplitude or completely cancelled out wave.

Late at night along the Mississippi River, a tugboat sounds its foghorn. The sound of the horn is heard as an echo 2.10 seconds later. If the sound travels at a speed of 341 m/s, then what is the distance from the tugboat to the reflecting surface?
What is 358.05 m
500
What the pitch of a sound is directly related to.
What is frequency (of the sound wave)

Hope and Faith are at Wrigley Field to watch the Cubs lose. They are sitting in the center field bleachers, a distance of 123 m from Home Plate. Assuming a speed of sound of 340 m/s, how much time (in milliseconds) would elapse between when they see the bat strike the ball and when they hear the sound of the bat striking the ball.
What is 361.76 ms
