[" 15) A dosed organ pipe ard an qper "],[" pipe of same length are set onto "],[" vibrations simultaraously.The beat frequency "],[" is "4." If the cength of each of them is "],[" doused then what is tho beat froguency? "]

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 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 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 2 beats when they are set into vibration simultaneously in fundamental mode. The length of the open organ pipe is now halved and that of the closed ogran pipe is doubled . What will be the number of beats produced ?

A closed organ pipe and an pipe of same length produce 4 beats when they are set into vibration simultaneoulsy. 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 pipe and an open pipe of same length produce 2 beats, when they are set into vibration simultaneously in their fundamental mode. If the length of the open pipe is halved, and that of closed pipe is doubled, and if they are vibrating in the fundamental mode, 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
