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 :
A1.0Correct AnswerIncorrect Answer
B1.2Correct AnswerIncorrect Answer
C1.5Correct AnswerIncorrect Answer
D2.0Correct AnswerIncorrect 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.
