A tube with one end closed and one end open resonates for a wave with wavelength λa as shown. The next shorter wavelength at which resonance will occur is λb. The ratio of these two wavelengths λa/λb is
Correct Answer: D
D Resonance occurs at λ = for odd integers. This means at 4L, L, L,…. We are shown a picture where a wave is in a tube of length L. This means λa = . The next shorter wavelength is λb = . The ratio of these is or or .
