Question

If an open pipe of length vibrates in fundamental mode, then pressure variation is maximum

A) at two ends
b) at the middle of pipe
c) at distance L/4 inside the ends
d) at distance L/8 inside the ends

Answer 1

at the middle of pipe

Step-by-step explanation:

ANSWER WILL BE AT THE MIDDLE OF THE PIPE

Answer 2

(B) at the middle of the pipe

Step-by-step explanation:

In the case of an open pipe which vibrates in fundamental mode, an anti-node is formed at the middle of the pipe, here the amplitude of the wave is maximum. Hence, the pressure variation is also maximum at the middle.
