Rearranging a wave function

  1. Aug 3, 2011 #1
    1. The problem statement, all variables and given/known data
    Consider the wave described by:
    E= 3 sin [pi (x/c - t)*10^13+ pi/6]

    True or false?
    34. The frequency = 10E13 Hz.
    35. The wavelength = 3E-6 m.
    36. The direction of motion: positive x direction.
    37. The speed = 300 000 km/s.
    38. The maximum amplitude = 9
    39. The initial phase = π/c
    40. It is linearly polarised.

    2. Relevant equations

    3. The attempt at a solution

    I'm trying to arrange it into the form E=Asin 2 pi f ((x/v) ± t).

    I think you will need to include a phase term in this.

    What have you tried?
