An electric field propagating in a lossless non-magnetic media is characterized by E(y, t) = 100cos(4 pi times 10^6 t - 0.1257y)a_z V/m
a) Find the wave amplitude, frequency, propagation velocity, wavelength, and the relative permittivity of the media.
b) Find H(y, t).

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
