Answer 1

It would decrease

Step-by-step explanation:

The formula for the velocity of a wave is given as: v = f * λ where v is the velocity of the wave, f is the frequency and λ is wavelength. The formula can also be written as: f=v/λ. From this we can see that frequency and wavelength are inversely proportional, meaning, when one increases, the other decreases.

Let's substitute in some random numbers: 10=40/4. If the wavelength increase (we put 5 instead of 4), then 8=40/5
