Quincke’s tube Examples

In Quincke's tube experiment the difference in amplitudes is due to

Quincke’s Tube|| Sonometer||Kundt’s Tube|| Doppler Effect|| Echo

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 :

Warming ammonium chloride with sodium hydroxide in a test tube is an example of :

Examples on viscosity||Reynolds’s number||Examples on terminal velocity

In Quincke's experiment the sound detected is changed from a maximum to a minimum when the sliding tube is moved through a distance of 2.50 cm. Find the frequency of sound if the speed of sound in air is 340 m s^-1 .
