The time period of a sound wave is 0.020 s. What is its frequency?
Question
The time period of a sound wave is 0.020 s. What is its frequency?
Solution
The frequency of a wave is the reciprocal of the time period.
Step 1: Identify the time period of the wave. In this case, the time period (T) is given as 0.020 seconds.
Step 2: Calculate the frequency (f) using the formula f = 1/T.
Step 3: Substitute the given time period into the formula.
f = 1/0.020 = 50 Hz
So, the frequency of the sound wave is 50 Hz.
