A wave travelling in the positive x -direction having displacement along y -direction as 1 ~m , wavelength 2 m and frequency of 1 Hz is represented by

Options

  1. Ay= (x-2 t)
  2. By= (2 x-2 t)
  3. Cy= (10 x-20 t)
  4. Dy= (2 x+2 t)

Correct answer

A. y= (x-2 t)

Step-by-step solution

Given a=1 ~m As, aligned y & = asin (k x- t) & = ( 2 2 x-2 1 t ) & = (x-2 t) aligned
