MHT CET 2026 Physics question
In fundamental mode, the time required for the sound wave to reach upto the closed end of a pipe filled with air is second. The frequency of vibration of air column is = wavelength of the wave
Answer: (B)
Solution
In a pipe closed at one end, the fundamental mode has a node at the closed end and an antinode at the open end, so the length of the pipe is . The sound wave travels this length in time , so . The frequency is ,
