Answer:
Long
Step-by-step explanation:
In a wave, frequency and wavelength have a relationship of inverse proportionality. In fact, the equation that relates frequency and wavelength for a wave is:
![\lambda=(v)/(f)](https://img.qammunity.org/2019/formulas/physics/college/nj7b2i6i6mufxqnx4v2d92wd9hq0fpnzw6.png)
where
is the wavelength
v is the speed of the wave
f is its frequency
In this problem, we have a wave with a low frequency: from the formule above, we see that when the frequency is low, the wavelength is long, and viceversa. So, the correct answer is
long
