Question

If a tuning fork has 75 Hz, how many cycles per second does it vibrate?

Answer 1

N = 75 cycles per second

Step-by-step explanation:

As we know that frequency is defined as the number of cycles per second

so here we can say that frequency is same as the number of cycles per second

so here given that

`frequency = 75 Hz`

so here we have

Number of cycles per second = 75 Hz

Answer 2

The frequency is defined as the number of vibrations (or number of cycles) per second. For example, if a certain device oscillates with frequency of 1 Hz, it means it makes 1 complete vibration/cycle each second. The tuning fork in this problem has a frequency of f=75 Hz, therefore it makes exactly 75 cycles per second.
