Question

A musical instrument takes 2 seconds to complete 200 oscillations then calculate frequency of it​

Answer 1

Answer:

Frequency = 100 hz

Explanation:

Number of oscillations executed in one second is called frequency.

[ Frequency = Total no. Of oscillation/total time taken. ]

Solution :

Frequency = 200/2

= 100 hz

So, the frequency is 100.

The time period to complete one oscillation is called periodic time.

Periodic time = 1/frequency

= 1/100

= 0.01

Frequency is 100 and p.time is 0.01 sec.

Answer 2

it's answer is 100 hertz
