A ray of green light traveling in a glass slab (with the index of refraction 1.67) strikes the interface with the air at 30 degrees to the normal. Find the critical angle of total internal reflection and conclude if the light would refract out to the air. in degrees, 2 significant figures A. 36.8, will not refract out, totally internally reflect B. 53.2, will not refract out, totally internally reflect C. 53.2, will refract out D. 36.8, will refract out
