Question

The period of a mechanical wave is 12 seconds. What is the frequency of the wave?

12 waves/second
4.0 waves/second
0.083 waves/second
depends on the speed of the wave

Answer 1

I'm pretty sure the answer is 0.083

have a good day =)

Answer 2

Data:
T (period) = 12 s
f (frequency) = ? (waves/second)

Formula:

`f = (1)/(T)`

Solving:

`f = (1)/(T)`

`f = (1)/(12)`

`\boxed{\boxed{f \approx 0.083\:waves/second}}\end{array}}\qquad\quad\checkmark`
