Which part of the wave has the highest frequency

Part F

Explanation:

The total number of oscillations or vibrations in a medium of a wave is called the frequency of this wave. The part where the wave has highest frequency is F. Here, the time period between the wave is very less.

The time period between time period and the frequency of the wave is given by :

=  frequency of the wave.

In part F, the spacing between consecutive waves is least. So, part F will has highest frequency.
