Practice portal › Waves › Progressive Waves and the Displacement Relation

The displacement of a wave travelling in the x-direction is y=10⁻⁴ sin (600t-2x+π/3) m, with x in metres and t in seconds. The speed of the wave motion, in m s⁻¹, is

Asked in JEE Main 2003 · Wave parameters from the equation

Answer: (1) 300

Step-by-step solution

ω=600 rad s⁻¹ and k=2 m⁻¹.

v=ω/k=(600)/2=300 m s⁻¹.
