what is the difference between TOTOL INTERNAL REFLECTION AND REFLECTION AT a PLANE SURFACE

Asked by vedant | 21st May, 2014, 02:22: PM

Expert Answer:

Reflection at a plane surface is a type of reflection. Here, a light ray is reflected from the reflecting surface to the same medium.
Total Internal Reflection is due to refraction. Here a light ray travelling from denser medium to a rare medium is reflected in the same medium instead of refracting in the rarer medium.
