Two vibrating strings ' ' and ' ' produce beats of frequency . The beat frequency is found to reduce to if the tension in the string is slightly reduced. If the original frequency of is , then the frequency of ' is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
The frequency of the string, A, fA =320 Hz Frequency of string B=fB Beat’s frequency,n=8 Hz. Beat's Frequency is given as: n=fA-fB⇒8=fA-fB=320-fB⇒fB=312 Hz & 328 Hz Frequency decreases with a decrease in the tension in a…
