Two tuning forks of frequencies 256 Hz and 258 Hz are sounded together. The time interval between two consecutive maxima is

Options

  1. A250 s
  2. B252 s
  3. C2 s
  4. D0.5 s

Correct answer

D. 0.5 s

Step-by-step solution

When two tuning forks of frequencies 256 Hz and 258 Hz are sounded together, the time interval between consecutive maxima corresponds to the beat period. The beat frequency is given by the absolute difference: f_ beat = |256 - 258| = 2 Hz . Therefore, the beat period is T_ beat = 1 f_ beat = 1 2 = 0.5 s . The correct option is D.
