Question

Two tuning forks A and B are sounded together and it results in beats with frequency of 4 beats per second. When A is loaded with wax, they again produces 4 beats per second. If frequency of A is 256 Hz , then the frequency of B is, 252 Hz, 262 Hz, A and B both, None

MARKS App · Accepted Answer

Since A produces four beats with B . So, frequency of B could be 260 Hz or 252 Hz . After waxing, frequency decreases. So, frequency of B has to be less than 256 Hz as it produces same number of beats with A . So, the frequency of B is 252 Hz ..
