Sound waves move through some liquid at a speed of 1500 m/s. If the wavelength is 3 m, what is the frequency of the wave?

A.1503 Hz
B.0.002 Hz
C.500 Hz
D.4500 Hz

500Hz

Explanation:

Frequency=velocity/wavelength

Frequency=1500/3

Frequency=500Hz

C.500 Hz

Explanation:

the information we have about the sound wave:

speed:

wavelength:

--------------

To find the frequency of the wave we need to use the following equation:

where is the velocity, is the frequency, and is the wavelength.

clearing for the frequency:

and susbtituting the values:

and since the units of frequency in are Hertz [Hz]

the frequency is:

which is option C
