Quincke's tube is used

A Quincke's tube is used

Kundt's tube can be used to

If the velocity of sound is V, velocity of the observer is V_(0) and the velocity of the source is V_(s) , then the necessary condition for the Doppler effect to hold good is -

In Quincke's tube a detector detects minimum intensity. Now one of the tube is displaced by 5 cm. During displacement detector detects maximum intensity 10 times, then finally a minimum intensity (when displacement is complete). The wavelength of sound is :
