As the number of cycles per second increases, the sound we perceive __________.
As the number of cycles per second increases, the sound we perceive __________.
Homework Answers
The number of cycles of the sound wave per second is known as
frequency.
Frequency is directly proportional to the number of cycles per
second.
So as the number of cycles per second increases, the frequency
increases.
As a result, the sound we perceive GETS HIGHER
Add Answer to:
As the number of cycles per second increases, the sound we
perceive __________.

2. A source is moving past a sound sensor in an unknown medium. The frequency detected in front of the source was 2700 cycles per second, and the frequency detected behind the source was 1300 Hertz. The object was clocked by a radar gun to be moving at 21 m/s. What is the speed of sound in the medium?
