Question

George is studying a mechanical wave. He counts thirty crests of the wave pass through a point in 10 seconds.

If What is the frequency of this wave?
Select one:

2 Hz.

20 Hz.

3 Hz.

30 Hz.

Answer 1

Option C

Step-by-step explanation:

Frequency determines the number of waves that pass through any defined point in a given time period.

Frequency of 1 hertz means that one wave travels through a given point in one second.

By the above definition, we can say

Frequency

`= (30)/(10) \\=3`

Hence, option C is correct
