Wave Motion 1 Question 7

7. A travelling wave in a stretched string is described by the equation ; y=Asin(kxωt)

The maximum particle velocity is

(1997, 1M)

(a) Aω

(b) ω/k

(c) dω/dk

(d) x/ω

Show Answer

Answer:

Correct Answer: 7. (a)

Solution:

  1. This is an equation of a travelling wave in which particles of the medium are in SHM and maximum particle velocity in SHM is Aω, where A is the amplitude and ω the angular velocity.
