How To Calculate Refractive Index From Critical Angle . When light travels from a dense material into one that is less dense, and at a certain oblique angle, it’s possible that ray of light will emerge parallel to the surface of the denser material (or at an angle of incidence, for which the angle of refraction is 90°).we call it the.
