Answer:
A: has a shorter wave length
Explanation:
As we know that the there is no relation between the frequency and the ampitude. But there is an inverse relation with respect to the wavelength i.e. if one is rise than the other would decrease. In addition to this, the shorter the
wavelength, the smaller would be the frequency and vice versa.
So if X contains the greater frequency so it has a shorter wave length
hence the option A is correct
