Propagation Of Sound Waves

Will there be Doppler effect, when the direction of motion of the source or observer is perpendicular to the direction of propagation of sound ?

Velocity of sound is v. Source and observer move towards each other with velocities V_(s) and V_(0) respectively. Wind is blowing with a velocity v_(m) in the direction opposite to the propagation of sound, n is the frequency of the sound. The apparent frequency of the sound heard by the observer is :-

Discuss the role of medium in the propagation of sound.

The pressure variations in the propagation of sound waves in gaseous medium are

What is the cause for production of sound ? Can sound propagate in vacuum?

Answer true or false A medium is not necessary for the propagation of sound

According to Laplace correction, the propagation of sound in gas takes place under
