Question
You are given four tuning forks, the lowest frequency of the forks is 300 Hz. By striking two tuning forks at a time any of 1, 2, 3, 5, 7 & 8 Hz beat frequencies are heard. The possible frequencies of the other three forks are-
- 301,302 & 307
- 300,304 & 307
- 301, 303 & 308
- 305, 307 & 308
The correct answer is: 301, 303 & 308
