3. A flat, monochromatic electromagnetic wave with a frequency of 4.5 X10 ¹4 Hz propagates in a vacuum in the direction of the X axis, the amplitude of the electric field is 92 V/m and it vibrates in the direction of the Z axis. This wave is incident on an interface corduroy parallel to the YZ plane, which separates a medium with refractive index n=1.62. 3.1. Determine the expression for the incident electric field, (with amplitude, frequency, wavelength...). (10 points) 3.2. Determine the expression for the electric field inside the material, E, (with amplitude, frequency, wavelength...) (10 points) 3.3. Determine the expression for the incident electric field, E, (with amplitude, frequency, wavelength...) (10 points) 3.4. Determine the irradiance of transmitted light (I) (10 points)
