3) A ray of light with a frequency of 5.09 x 1014 hertz traveling in medium X is refracted at point P. The angle of refraction is 90.0, as represented in the diagram. A) Calculate the wavelength of the light ray in air. B) Measure the angle of incidence for the light ray incident at point P. C) Calculate the absolute index of refraction for medium X. Normal Air P Refracted ray Incident ray Medium X f = 5.09 x 1014 Hz sheup beau
