A closed organ pipe and an open pipe of same length produce 6 beats per sec when they are set into vibrations simultaneously with their fundamental frequency. If the length of each pipe is doubled, then the number of beats produced is

A closed organ pipe and an open organ pipe of same length produce 2 beats when they are set into vibrations simultaneously in their fundamental mode. The length of open organ pipe is now halved and of closed organ pipe is doubled, the number of beats produced wil be (A)8 (B)7 (C)4 (D)2

A closed organ pipe and an open organ pipe of some length produce 2 beats when they are set up into vibration simultaneously in their fundamental mode . The length of the open organ pipe is now halved and of the closed organ pipe is doubled , the number of beats produced will be a) 7 b) 4 c) 8 d) 2

A closed organ pipe and an open organ pipe of same length produce 4 beats when they are set into vibration simultaneously. If the length of each of them were twice their initial lengths. The number of beats produced will be [Assume same mode of viberation in both cases]

A closed organ pipe and an open organ pipe of same length produce 4 beats when they are set into vibrations simultaneously. If the length of each of them were twice their initial lengths, the number of beats produced will be

A closed organ pipe and an open organ pipe of same length produce 2 beats/second while vibrating in their fundamental modes. The length of the open organ pipe is halved and that of closed pipe is doubled. Then, the number of beats produced per second while vibrating in the fundamental mode is

The fundamental frequency of a vibrating organ pipe is 200 Hz.

A closed organ pipe and an open organ pie of same length produce four bets in their fundamental mode when sounded together, If length of the open organ pipe is increased, then the number of beats will

A closed and an open organ pipe have the same length. When they are vibrating simultaneously in their first overtone, they produce three beats. The length of the open pipe is now made one third the original length and one of its ends is closed. On the other hand, the length of the closed pipe is made three times the original length. The number of betats produced when they vibrate with fundamental frequencies will be

A closed organ pipe and an open organ pipe are tuned to the same fundamental frequency. The ratio of their lengths is

A closed organ pipe and an open organ pipe are tuned to the same fundamental frequency. The ratio of their lengths is
