A snapshot graph of an EM plane wave is shown below. The electric field is parallel to the y-axis and the magnetic field is parallel to thez-axis. The points labeled 1, 2 and 3 are in the (x,y) plane.

Rank the magnitude of the magnetic field at points 1, 2 and 3. If field is 0 at any of these points, state so explicitly. Explain. 1, Rank the magnitude of the magnetic field at points 1, 2 and 3. If field is 0 at any of these points, state so explicitly. Explain.

2,What is the direction of propagation of the plane wave? Explain.

3,If the wavelength of the plane wave is ? = 600 nm and the magnitude of the electric field is E₀ = 10 V/m, come up an expression for the B field in the form B = B₀sin(Cx + Dt) .

Give the values of B₀, C and D.

Take for the speed of light c = 3x10⁸ m/s
