Light with a wavelength of 600 nm is incident on a gemstone made of cubic zirconia (ᡦ =2.18) from air. the light makes an angle of 30° with the surface of the gem before entering it. the refracted ray makes an angle of 30° with the normal. what is the frequency of the light in the gemstone? (1 thz = 1 terahertz =10ଵଶ hz)
