Two tuning forks of frequencies 256 Hz and 258 Hz are sounded together. The time interval between two consecutive maxima is
- A 250 s
- B 252 s
- C 2 s
- D 0.5 s
Answer & Solution
Correct Answer
(D) 0.5 s
Step-by-step Solution
Detailed explanation
\(f_{\text{beat}} = |f_1 - f_2| = |256 \, \text{Hz} - 258 \, \text{Hz}| = 2 \, \text{Hz}\) \(T_{\text{beat}} = 1/f_{\text{beat}} = 1/(2 \, \text{Hz}) = 0.5 \, \text{s}\)
