Question

A sinusoidal plane electromagnetic wave travels in a vacuum in the x direction as shown in the graph. The period of the wave is T = 3.5 × 10^-8 s.

Please just answer d-g i already got a-c

(a) Express the wavelength of the wave, λ, in terms of T and the speed of light, c.

answer: λ=cT

(b) Solve for the numerical value of λ in m.

answer: 10.5

(c) Write the equation of the frequency, f, in terms of T.

Answer: λ=1/t
(d)  Solve for the numerical value of f in Hz.
(e)  The magnetic field reaches its maximum value, B_max = 6.8 x 10^-6 T, in the z direction at some point and at some instant. Express the magnitude of the electric field at this position and time, E_max, in terms of B_max.
   (f)  Solve for the numerical value of E_max in V/m.
  (g)  What is the direction of the electric field at this position and time?
