Solution

The correct option is C TTF
Wavelength is defined as the distance between two adjacent crests or two adjacent troughs in a wave.
Frequency is defined as the number of waves that pass a given point in one second. The unit of frequency is s1.
The maximum displacement showm by a point on a wave measured from its equivalent position is known as the amplitude whereas a wave number is the number of wavelengths per unit length. It has a unit of m1.
