Question

Number of vibrations per second is called ___________ (Fill in the blank)

Answer 1

The number of vibrations per second is called frequency. Also, it can be called as temporal frequency, which focuses on the difference between angular and spatial frequency.

One more way to define frequency is that it is the reciprocal of period, which is the overall duration of time of an event that occurs repeatedly.

Answer 2

Number of vibrations per second is called frequency.

The rate at which something occurs over a particular period of time or in a given sample is known as frequency.

Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as Temporal Frequency, which emphasizes the contrast to spatial frequence and angular frequency.
