Question
A wave on a starting is travelling and the displacement of particles on it is given by x = A sin (2t - 0.1 x). Then the wavelength of the wave is
Options
A.10 π
B.20 π
C.40 π
D.40
Solution
x = Asin (2t - 0.1x)
also x = Asin
⇒
= 0.1   ⇒ 20 π
also x = Asin
⇒
= 0.1   ⇒ 20 πCreate a free account to view solution
