Question

Two tuning forks of frequency 520 Hz and 524 Hz are vibrated together. The time interval between successive maximum and minimum intensities is

Answer 1

Hello Dear.

Here is the answer---

→→→→→→→→

f₁ = 520 Hz.
f₂ = 524 Hz.

Time Interval = 1/(f₂ - f₁)
                      = 1(524 - 520)
                      = 1/4 seconds.

Thus, Time Interval Between the Maximum and Minimum Intensities is 0.25 seconds.

Hope it helps.

Answer 2

Two tunnig fork of frequency 520 Hz and 524Hz are vibrated together. It means beats form due to it .
f₁ = 524 Hz
f₂ = 520 Hz
Beat period = 1/number of Bea are formed per unit time
= 1/(f₁ - f₂)
= 1/(524 - 520)
= 1/4 sec

Now, time inveral between successive maximum and minimum intensities = beat period= 1/4 sec
