Question

  If a light travels in a certain medium and it gets reflected off an optically denser medium with high
refractive index,then it is regarded as_______​

Answer 1

Answer:

There are two laws of reflection :-1) According to the first laws of reflection ,the incident ray,reflected ray,and the normal all are lie in the same line..2) According to the second law of reflection the angle incidence is always equal to the angle of reflection..

Answer 2

Answer:

External Reflection

Explanation:

Total external reflection is the situation where the light starts in air and vacuum (refractive index 1), and bounces off a material with index of refraction less than 1.

The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle.
