Asound wave in the air has a frequency of 256 hertz and is traveling at a speed of 331 meters/second. what is its wavelength?

1.52 meters

1.29 meters

2.39 meters

0.500 meters

10.0 meters

The correct answer is 1.29 m/s.

Explanation:

The expression for the velocity of the wave is as follows;

Here, f is the frequency of the wave, v is the velocity of the wave and is the wavelength of the wave.

It is given in the problem that a sound wave in the air has a frequency of 256 hertz and is traveling at a speed of 331 meters/second.

Calculate the wavelength of the wave by rearranging the above expression.

Put v= 331 m/s and f= 256 Hz by rearranging the above expression.

Therefore, the wavelength of the wave is 1.29.
