Question

4 complete waves pass a given point in 8 seconds, what is the frequency of the wave?

Answer 1

`0.5` Hz

Explanation:

A frequency of `1` Hz corresponds to one complete wave passing a point each second.

If `4` waves pass a point in `8` seconds then the frequency is:
`4/8 = 1/2 = 0.5` Hz.

The basic formula for frequency can be thought of as:
`nu = (n um waves)/(time)`
