Definition. No. If there is no change in speed there is no refraction. If there is no refraction, there is no dispersion of light and hence, no rainbow! Term. The minimum angle of incidence for which a light ray is totally reflected within a medium is called the ______________ _______________. Definition. critical angle. Term. The 100% reflection (with no transmission) of light that strikes the boundary between two media at an angle greater than the critical angle is called _______ ________ ________.
