What are linear sound waves and non-linear sound waves

Determine the frequency of sound, when successive maximum and minimum were detected $2.5 \mathrm{cm}.$apart  ia a Quincke's tube experiment.( the velocity of sound =$340\mathrm{m}/\mathrm{s}$ )

The speed of the sound can be determined by using Quincke's. tube. This apparatus is based  on the phenomenon of :

What is the principle of measuring the speed of sound by Quincke's tube.

What is  the Quincke's tube?

What do you understand by the interference of waves? Explain constructive and destructive interference of waves.

In a stretch string, two waves of the same amplitude, each of $5.0 \mathrm{mm}$travel in the same direction. The phase difference between the waves is $60°$ and they interfere with each other. Find the amplitude of the resultant wave

Two loudspeakers are placed at either end of a gymnasium, both pointing towards the centre of the gym and equidistant from it. The speakers emit $266 \mathrm{Hz}$ sound that is in phase. An observer at the centre of the gym experiences constructive interference.How far must the observer walk to go from one point of constructive interference to the next? ( velocity of sound =$343 \mathrm{m}/\mathrm{s}$)

Which of the following statement is not true for the phenomenon of interference?

Derive the conditions for the resultant intensity after interference of two waves.

An organ pipe open at both ends produces:

The disturbances produced by two sound sources cannot be cancelled as the disturbance by each wave is added.

What do you understand by principle of superposition of waves?

Three waves of equal frequencies having amplitudes $10 \mathrm{\mu m}, 4 \mathrm{\mu m}$ and $7 \mathrm{\mu }\mathrm{m}$ arrive at a given point with successive phase difference of $\frac{\pi }{2}.$ The amplitude of the resulting wave in $\mathrm{\mu }\mathrm{m}$ is given by, 

The diagram shows the propagation of a wave. Which points are in same phase?

Two waves are passing through a region in the same direction at the same time. If the equation of these wave are

$y_1=a\sin \frac{2\pi }{\lambda }\left(vt-x\right)$

$y_2=b\sin \frac{2\pi }{\lambda }\left[\left(vt-x\right)+x_0\right]$,

then the amplitude of the resultant wave for $x_0=\frac{\lambda }{2}$ is,
