Question

write the value of the product of frequency and time period

Answer 1

Frequency is the rate of oscillation, or number of oscillations in unit time.
$t= \frac{1}{f}$
Their product will be 1.

Answer 2

Answer:  

The value of the product of frequency and time period is 1.

Explanation:

The product of frequency and time period is 1. As we know that frequency is defined as the number of oscillations per unit time. Such as  

$\bold{\text { Frequency }=\frac{\text { Number of oscillations }}{\text { Time }}=\frac{1}{\text { Time }}}$

As the number of oscillations is considered as a single complete cycle so number of oscillations will be 1. Then, the product of frequency with time will be giving the total distance covered in case of circular motion as it will be giving number of oscillations which is 1.
