MHT CET 2023 Physics question
In resonance tube, first and second resonance are obtained at depths 22.7 cm and 70.2 cm respectively. The third resonance will be obtained at a depth
Answer: (A)
Solution
In a resonance tube (closed pipe) successive resonances are separated by half a wavelength: . Here (so ). The third resonance occurs at $ = + = 70.2 + 47.5 = 117.7\
