Please do not give me a theoretical approach,,This is a real question that needs real answers If you dont know how to solve do not solve. Please provide clear image and handwriting so that I know how to solve this. Thanks

plane wave traveling in a medium with ,-9 is normally incident upon a second medium with ,,-4. Both media are made of nonmagnetic, nonconducting materials. If the magnetic field of the incident plane wave is given by El- 2cos(2 x 109t-ky) (A/m) Obtain time-domain expressions for the total electric and total magnetic fields in each of the two media. Determine the average power densities of the incident, reflected, and transmitted waves. a. b.

Explanation / Answer

in the given question the wave is travelling along the y direction so there will be no component along the y direction but in the given question the component and the direction are same which is wrong

so it is not a valid expression

and it is assumed that if a wave is travelling along the y direction there should not be any component along that direction
