Q

How does sound travel through a medium?

A

Wave motion

22
Q

In the study of physics, range of compression wave frequencies to which the human ear is sensitive?

A

Sound

23
Q

To distinguish frequencies in the audible range from those outside that range, the words (a) are used. Sounds capable of being heard by the human ear are called (b). The normal hearing range extends from about 20 to 20,000 hertz. However, to establish a standard sonic range, the Navy has set an arbitrary upper limit for sonics at (c) and a lower limit at (d).

A

(a) Sonic, Ultrasonic, Infrasonic
(b) Sonics
(c) 10,000 hertz
(d) 15 hertz

24
Q

Sound heard by ear?

A

Sonics
