Question 18 0 / 5 pts 18) A ray of light poing from one material into another follows the path shown in the figure below. What can you conclude about the relative indexes of refraction of these two materials? 0/ 5 pts Question 19 19) A ray of lighe follows the path shown in the figure below as it reaches the boundary between two transporent materials, What can you conclude about the relative indees of refraction of these two materials In

Answer 1

Problem 18)

Angle of incidence > Angle of emergence

=> na > nb

Problem 19)

When light passes from denser medium to rarer medium and the angle of incidence is greater than critical angle then the light is totalinternal reflected.

So, n ₁ < n ₂
