Question

The period of a mechanical wave is 4 seconds. What is the frequency of the wave? 8.0 waves/second 4.0 waves/second 0.25 waves/second depends on the speed of the wave

Answer 1

The formula for finding the frequency of a wave is with the following formula:
F = 1/T, F being the variable for frequency and T substituting as time. Given we already have our time, let's plug it in for T.
F = 1/4. This means our answer is in some mathematical form that is equivalent to 1/4. We have the answer "0.25 waves/second", which is equivalent to our original fraction (0.25 x 4 = 1.00).

I hope this helps!

Answer 2

Hello!

Data:

T (period) = 4 s

f (frequency) = ? (waves/second)

Formula:

`f = (1)/(T)`

Solving:

`f = (1)/(T)`

`f = (1)/(4)`

`\boxed{\boxed{f = 0.25\:waves/second}}\end{array}}\qquad\quad\checkmark`
