Question

The sound of a loud warning siren travels through air and reaches the surface of a lake. The sound is then transmitted through the water at a speed about four times faster than through air. How will the frequency and wavelength in water compare to these same measurements in air?

Answer 1

The frequency of a transmitted wave always stays the same. If the velocity is 4 times greater the wavelength must also be 4 times greater.

Step-by-step explanation:

Answer 2

The wavelength will increase by a factor of four, but the frequency will not change.
