Question

Two tuning forks have frequencies 450 Hz and 454 Hz respectively. On sounding these forks together, the time interval between successive maximum intensities will be

• A. 1/4 sec
• B. 1/2 sec
• C. 1 sec
• D. 2 sec

Answer 1

Answer: (A)

1/4 sec

Answer 2

The time interval between successive maximum

intensities will be $\frac{1}{n_{1}\sim n_{2}} = \frac{1}{454 - 450} = \frac{1}{4}sec.$
