Question

A source vibrates _ number of times in a minute if it’s frequency is 100 hz

Answer 1

Frequency - The number of complete vibrations/oscillations completed by an oscillating body in 1 sec is called it's frequency.

SI unit - Hertz (symbol: Hz)

1 Hz means the body completes 1 full oscillation in 1 sec.

20 Hz means the body completes 20 full oscillation in 1 sec.

Given:- 100 Hz

This means the body completes 100 complete oscillations in 1 sec

=> The body completes 100*60 complete oscillations in 60 sec(1 minute)

In other words,

==> A source vibrates 6000 number of times in a minute.
