Questions
Two sinusoidal waves with same wavelengths and amplitudes travel in opposite directions along a string with a speed 10 ms–1. If the minimum time interval between two instants when the string is flat is 0.5 s, the wavelength of the waves is
detailed solution
Correct option is D
Minimum time interval between two instants when the string is flat = T2=0.5sec⇒T=1secHence λ=v×T=10×1=10 m.Talk to our academic expert!
