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).
