FM radio wave at 150 MHz travels along the x-axis with a magnetic field polarized along the z axis, width Bmax = 10^-4 T. The wave is reflected οn metal surface which intersects vertically the course of the wave at position x = 0. After reflection, the electric field changes phase by 180o but its width as well as its magnetic field remains the same. a) Write the expressions for the electric and the magnetic field of the incident and reflected EM wave. b) Calculate the parameters λ, β, ω, Ε max, the intensity and density of energy per unit volume of the EM field, as well as the force exerted by the EM radiation on surface if it has an area of 500 m^2. (c = 3x10^8 m/s, μ0, ε0 known).
In Figure (a) below, unpolarized light is sent into a system of three polarizing sheets. The angles 8₁, 82, and 83 of the polarizing directions are measured counterclockwise from the positive direction of the y axis (they are not drawn to scale). Angles 8₁ and 83 are fixed, but angle 82 can be varied. Figure (b) gives the intensity of the light emerging from sheet 3 as a function of 82. (The scale of the intensity axis is not indicated.) What percentage of the light's initial intensity is transmitted by the system when 82 = 34⁰? (a) M 90° (b) 18002
