In the experiment for the determination of the speed of sound in air using the resonance column method, the length of the air column that resonates in the fundamental mode, with a tuning fork is 0.1 m. When this length is changed to 0.35 m, the same tuning fork resonates with the first overtone. Calculate [...]

Two sinusoidal waves with same wavelengths and amplitudes travel in opposite directions along a string with a speed 10ms^−1. If the minimum time interval between two instant when the string is flat is 0.5s, the wavelength of the waves is A transverse wave y=0.05sin(20πx−50πt) meters The resultant amplitude due to superposition of two harmonic waves [...]

Two waves are propagating to the point P along a straight line produced by two sources A and B of simple harmonic and of equal frequency. The amplitude of every wave at P is a and the phase of A is ahead by π/3 than that of B and the distance AP is greater than [...]

Two sources of sound A and B produce the wave of 350Hz, they vibrate in the same phase. The particle P is vibrating under the influence of these two waves. If the amplitude at the point P produced by the two waves is 0.3mm and 0.4 mm then the resultant amplitude of the point P [...]

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