Solution

The correct option is A
10 Hz

Here, total number of oscillations = 10
Total time taken = 1 s
Hence, time taken for 1 oscillation = $\frac{1}{10}$ s

The time required to complete one oscillation is known as time period (T).

Now, frequency, $f = \frac{1}{T}$ = 10 Hz

The time taken for 10 oscillations is 1 s. The frequency of the wave is:

The correct option is A 10 Hz Here, total number of oscillations = 10 Total time taken = 1 s Hence, time taken for 1 oscillation = 110 s The time required to complete one oscillation is known as time period (T). Now, frequency, f=1T = 10 Hz

The correct option is A
10 Hz

Here, total number of oscillations = 10
Total time taken = 1 s
Hence, time taken for 1 oscillation = $\frac{1}{10}$ s

The time required to complete one oscillation is known as time period (T).

Now, frequency, $f = \frac{1}{T}$ = 10 Hz
