As the frequency of a wave decreases, the wave's -

period decreases

speed decreases

wavelength increases

amplitude increases

wavelength increases, because when frequencies are decreased, wavelengths become longer.

Answer:

Wavelength increases.

Explanation:

The Speed of a wave is given by the product of its frequency and wavelength.

i.e ν = fλ, where ν is the wave speed, f is the wave's frequency, and λ is the wavelength.

So for the speed to have a constant value at an instance, then if the frequency decreases, the wavelength will increase and vice versa.
