Three sound waves of equal amplitudes have frequencies (n-1) ,n (n+1) .They superimpose to give beats.The number of beats produced per second will be

When two sound waves with a phase difference of pi //2 , and each having amplitude A and frequency omega , are superimposed on each other, then the maximum amplitude and frequency of resultant wave is

Two waves of equal frequencies have their amplitudes in the ratio of 3:5. They are superimposed on each other. Calculate the ratio of maximum and minimum intensities of the resultant wave.

Two waves of equal frequencies have their amplitude in the ratio of 5:3. They are superimposed on each other. Calculate the ratio of the maximum to minimum intensities of the resultant wave.

Two waves of nearly same amplitude , same frequency travelling with same velocity are superimposing to give phenomenon of interference . If a_(1) and a_(2) be their respectively amplitudes , omega be the frequency for both , v be the velocity for both and Delta phi is the phase difference between the two waves then ,

Two waves of same frequency but of amplitude a and 2a respectively superimpose over each other. The intensity at a point where the phase difference is (3pi)/(2) , will be proportional to :

Represent graphically by two separate diagrams in each case : (i) Two sound waves having the same amplitude but different frequencies. (ii) Two sound waves having the same frequency but different amplitudes. (iii) Two wound waves having different amplitudes and also different wavelengths.

The resultant amplitude, when two waves of two waves of same frequency but with amplitudes a_(1) and a_(2) superimpose at phase difference of pi//2 will be :-

When two sound sources of the same amplitude but of slightly different frequencies v_(1) and v_(2) are sounded simultaneously, the sound one hears has a frequency equal to
