Question

Fill in the blanks in the following with either "towards" or "away from": Rays refract _____ the medium with the higher phase speed. Rays refract _____ the medium with the higher index of refraction. In a fiber optic cable, the inner part is called the _____ while the outer part is called the _____. The index of refraction for the inner part is (circle one of the following: "greater than" or "less than") the index of refraction for the outer part. For the following questions, answer "yes" or "no": Can a TEM wave propagate in a waveguide? Answer._____ Can a TEM wave propagate in air? Answer: _____ A plane wave is obliquely incident upon the planar boundary between two media. The electric field is confined to the plane of incidence. The resulting field is said to be _____ polarized. If the skin depth of a material is 2 cm, at what depth does the power in the transmitted wave fall to e^-1 (37%) of what it was at the interface? For a plane wave propagating in air. E = E_ x and H = H_ z where H_, = E_/eta_0. In what direction is the plane wave propagating? Fill in the following with "increases" or "decreases". As the beam width of an antenna decreases, the gain _____ In about 20 words or less, explain reciprocity for antennas. A 3 GHz plane wave is normally incident from air onto a highly conducting copper sheet. The resulting pharsor for the total E-field in air is given by E_1(z) = -x2 j E^i_0 sin (k_1 z). What is the Corresponding times-domain expression for the E-field?

Explanation / Answer

(5)

Ray is model of light and bending of wave is called as refraction. Based on speed it ray will bends.

The ray refract towards the medium with higher phase speed and away the medium with higher idexof refraction.
