Question
Two waves, each of amplitude 1.5 mm and frequency 10 Hz,
are travelling in opposite direction with a speed of 20 mm/s. The distance in mm between adjacent nodes is :Solution
Since the amplitudes, frequency and the speed of both the waves are in same, hence the wavelength of the composite wave will be the same as the single wave.
