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 BP by 50cm. Then the resultant amplitude at the point P will be if the wavelength 1 meter
