Question

If the frequency of a wave is 25 hertz ,what is the total number of compression and rarefaction passing through a point in 1 seconds

Answer 1

Answer:

We know from the question that here, the frequency of the wave = 25 Hz

1 Hz = 1 compression + 1 rarefaction

Therefore, 25 Hz = 25 compressions + 25 rarefactions = 50

Hence, the total number of compression and rarefaction passing through a point in 1 second = 50.

Answer 2

There are 50 compression and rarefaction passing through a point in 1 second.

Explanation:

If a wave move in the form of compression and rarefaction, then it must be a longitudinal wave. It is given that, the frequency of a wave is 25 Hz. We need to find the total number of compression and rarefaction passing through a point in 1 second.

We know that 1 hertz is equal to the sum of 1 compression and 1 rarefaction. Therefore, 25 hertz is equal to the sum of 25 compression and 25 rarefaction. So, there are 50 compression and rarefaction passing through a point in 1 second.
