Two parts of a sonometer wire, divided by a movable knife–edge, differ in length by 1 cm and produce 1 beat per second when sounded together. If the total length of the wire is 100 cm, the frequencies of the two parts of the wire are
- 51 Hz, 50 Hz
- 50.5 Hz, 49.5 Hz
- 49 Hz, 48 Hz
- 49.5 Hz, 48.5 Hz
Answer
(B) 50.5 Hz, 49.5 Hz
