The phasor magnetic field intensity for a 400 MHz uniform plane wave propagating in a certain lossless material is (2ay − j5az)e−j25x A/m. Knowing that the maximum amplitude of E is 1500 V/m, find β, η, λ, νp, r, µr, and H(x, y, z, t):

H = (ax - 5az)e-j25x A/m. Determine the values for K, εr, λ, vp and n in that order. Report your answer for Vp in terms of c, the speed of light in free space.

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
