    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 :
    A 1.0 Correct Answer Incorrect Answer
    B 1.2 Correct Answer Incorrect Answer
    C 1.5 Correct Answer Incorrect Answer
    D 2.0 Correct Answer Incorrect Answer

    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.
