Question

Now we use a tuning fork of frequency 302 Hz, instead of 300 Hz, with how much velocity should we move the tuning fork, so that resonance is created with the air column in any arm ?

(A) 2 m/sec. towards the tube

(B) 2 m/sec. away from the tube

(C) 4 m/sec. towards the tube

(D) 4 m/sec. away from the tube

Answer 1

Correct option: (B) 2 m/sec. away from the tube

Explanation:

For resonance appeared frequency for the tube should be still 300 Hz
