Suppose that a wave has a period of 0.03 seconds what is its frequency be sure to show the steps for your work

Reil [10]

Answer:

f = 33.34 Hz

Explanation:

A wave has a period of 0.03 seconds. It is required to find the frequency of a wave. The relation between time period and frequency is inverse. The time period of a wave is given by :

T = 1/f, f = frequency of wave

$f=\dfrac{1}{T}\\\\f=\dfrac{1}{0.03}\\\\f=33.34\ Hz$

So, the frequency of the wave is 33.34 Hz.
