For a resonance tube, the air columns for the first and the second resonance differ in length by `31.5 cm`. The wavelength of the wave isA. 31.5cmB. 63.0cmC. 126.0cmD. 252.0cm

Answer» Correct Answer - B
The first resonating length is `l_1+e=lamda/4`
The second resonating length is `l_2 +e= (3lamda)/(4)`
`l_2-l_1 = lamda//2 = 2xx 31.5=63cm`
