Voices of swimmers at a pool travel 400 m/s through the air and 1,600 m/s underwater. the wavelength changes from 2 m in the air to 8 m underwater. how has the change in media affected the frequency of the wave?

The frequency of the wave has not changed.

In fact, the frequency of a wave is given by:

where v is the wave's speed and is the wavelength.

Applying the formula:

- In air, the frequency of the wave is:

- underwater, the frequency of the wave is:

So, the frequency has not changed.

The change in media affected the frequency by a quarter.

The sound velocity (), in meters per second, is described by the following expression:

(1)

Where:

By (1), we get expression for the frequency:

Now we proceed to determine the frequency associated to each medium:

Water (, )

Air (, )

The change in media affected the frequency by a quarter.

We kindly invite to check this question on wavelengths: link

answer: what are you talking about?

explanation:

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
