MHT CET 2025 Physics question
An open organ pipe and closed organ pipe of same length produce 2 beats per second, when they are set into vibrations together, in fundamental mode. The length of open pipe is made half and that of closed pipe is doubled. The number of beats produced per second will be (neglect end correction)
Answer: (C)
Solution
Fundamental frequencies for length : open pipe , closed pipe . Beats: Hz, so Hz. New lengths: open pipe gives Hz;
