Question

Find the frequency of that wave whom time period is 0.04 second

Answer 1

according to the question A time period is the overall time that is required for the vibration to complete one cycle during a given point in time.

With the increase in the time period, the frequency of the wave decreases.

When the time period of a wave is 0.05 seconds

frequency = 1/the given time period, given that time period = 0.05 sec
then
f = 1/0.05
= 20 Hz ans

i hope its hlp you
follows me

Answer 2

Answer:

20 Hz

Explanation:

frequency = 1/ time period

                 = 1/0.05

                 = 1/5/100

                 = 1 × 100 / 5

                 = 20 Hz.
