In this lesson, we will learn how to describe sound wave propagation, define audible frequencies, and explain the applications of reflections of sound waves.
Which of the following sound waves is an example of ultrasound?
A sound wave in an object alternately compresses and expands it in the direction that the
wave travels. The sound has a wavelength of 0.48 m. What is the distance between the point
of maximum compression and the point of maximum expansion in the object?
A string on a violin is pushed by a bow and the string vibrates
at a frequency of 440 Hz. The sound waves produced by the vibrating string have
a wavelength of 0.75 m. What is the speed of the sound waves?
Which of the following sound waves is within the human hearing range?
Which of the following sound waves is an example of infrasound?
A submarine’s sonar scanner uses sound waves
that reflect from objects around the submarine.
The submarine emits sound waves vertically downward
and detects their reflection
The sea beneath the submarine is
deep. What is the speed of the sound waves?
Answer to the nearest meter per second.
A string on a guitar is pulled upward and released. The
string vibrates, returning to the position from which it was released 196 times
per second. What is the frequency of the sound wave produced by the string?
