Answer:
D. short wavelength
Step-by-step explanation:
The frequency of a wave is inversely proportional to its wavelength. In fact, the relationship between the two quantities is the following:

where
is the wavelength
v is the wave speed
f is the frequency
From the equation, we see that:
- the higher the frequency, the shorter the wavelength
- the lower the frequency, the longer the wavelength
So, a wave with a high frequency generally has a short wavelength.
