Daniela Greene · Answer 1

Answer: The frequency increases by a factor of 4.

Savannah · Answer 2

The product of (wavelength) x (frequency) is always the same number ... the wave's speed.

So if the wavelength is somehow reduced to 1/4 its original length, the frequency is immediately multiplied by 4. That's the only way their product can remain the same.
