Question

why refraction does not take place in diamond state reasons​

Answer 1

it's refractive index is very high so it's critical angle is very low so the easily total internal reflection happens . It is actually kind of refraction with angle more than ninty degree

Answer 2

Answer:

please mark me as the brainliest

Explanation:

There is no refraction takes place in diamond

because it has polished surface ;

which makes the angle of incidence >>> than critical angle

so there is only a total internal reflection takes place
