[A10]. Assume the incident angle is
30\deg
and speed of light in vacuum
C=3\times 10^(8)(m)/(s)
. If the wavelength of the light in the air is 500 nm , determine angle, speed, wavelength, frequency, energy, momentum, and direction of light in the mediums with
n2=1.5
and
n3=1.8
as shown in the figure. (show all the formulas and calculations, in order and complete and put the final values in a box to get the full mark.
