Transverse Waves :: Discussion


6.The displacement of particles in a string stretched in the x-direction is represented by y. Among the following expressions for y, those describing wave motion are?
A.coskxsinωt
B.k2 ω2-ω2 t2
C.cos2 (kx+ωt)
D.cos2 (k2 x2-ω2 t2)
Answer:  Option  A
Explanation:

y= coskxsinωt is the only equation of standing wave. The conditions for a function of x and t to represent a wave is
(∂2 y)/∂x2 = constant×(∂2 y)/∂t2
Only first expression satisfies this condition.
