Question

State the number of vibrations that occur in one second if the frequency of a wave is 60 Hz.

Answer 1

The total number of vibrations or number of cycles are 60. in one second.

Explanation:

We are given:

• Time period = 1 second
• Frequency of wave = 60 Hz

Solution:

As we know that:

The frequency of 60 hertz means that the source of sound vibrates 60 times in 1 second.

f = No. of vibrations / T

60 = No. of vibrations / 1

No. of vibrations = 60 x 1 = 60

Thus the total number of vibrations or number of cycles are 60. in one second.
