MHT CET 2024 Physics question
A wire of length 'L' and linear density 'm' is stretched between two rigid supports with tension 'T'. It is observed that wire resonates in the Pth harmonic at a frequency of 320 Hz and resonates again at next higher frequency of 400 Hz. The value of 'p' is
Answer: (B)
Solution
A string fixed at both ends resonates at , where is the fundamental frequency. Consecutive harmonics differ by : Hz. Then
