Questions
The equation of a travelling wave is given by
where x and y are in meter and t is in second. The velocity of the wave is
a
10 m/s
b
20 m/s
c
200 m/s
d
400 m/s
detailed solution
Correct option is B
Given, y=0.5sin (20x−400 t)Comparing with y=asin(ωt−kx)Gives velocity of wave v=ωk=40020=20 m/s.Talk to our academic expert!
