What is total internal reflection of light?

Expert Answer:

When light is incident from a denser to rarer medium the ray deviates away from the normal. For a certain angle of incidence (i = ic) the angle of refraction becomes 900. This angle of incidence is called the critical angle. Any ray with incident angle greater than this critical angle will be completely reflected back to the denser medium. This phenomenon is called Total Internal Reflection.
