A progressive wave travelling in a medium is represented by the equation y = A ( t - x) , where y , x , and t are in SI units. The wavelength of the wave is given by:

Options

  1. A2
  2. B2
  3. C2

Correct answer

A. 2

Step-by-step solution

The given equation of the progressive wave is y = A ( t - x) . Comparing this with the standard equation of a progressive wave y = A ( t - k x) , we get the angular frequency = and the wave number k = . The wave number k is related to the wavelength by the relation k = 2 . Substituting k = , we get = 2 . Therefore, the wavelength is = 2 . Answer: 2
