Assertion: The length of the glass tube ...

Assertion: The length of the glass tube in air column resonating experiment is 75 cm. If velocity of sound in air is `330ms^(-1)`, The experiment connot be performed with a tuning fork o frequency n=482 Hz.
Reason: If `l_(2)andl_(1)` are first and second resonating lengths in air column resonating experiment, then velocity of sound `V=2n(l_(2)-l_(1))`
