How many vibrations per second are associated with a 101-mhz radio wave?

vibrations per second

Explanation:

The frequency of a wave corresponds to the number of vibrations per second:

(1)

where N is the number of vibrations per second.

In this problem, the frequency of the radio wave is

And substituting into eq.(1), we find N:

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
