total internal reflctn occur4rm a dense 2a less dense medium. so
ans shud be D
cos its 4rm less dense2 a denser medium
The answer is D. Total internal reflection occurs when a ray of light passes from an optically more dense medium to a less dense one. Glass is less dense than water, judging by their refractive indices.
Total internal reflection occurs when light travels from a denser medium to a less dense medium at an angle of incidence greater than the critical angle. The critical angle is the angle of incidence that results in an angle of refraction of 90 degrees.
So, looking at the options:
A. Water to air: Total internal reflection can occur here if the angle of incidence exceeds the critical angle.
B. Water into glass: Total internal reflection can occur here if the angle of incidence exceeds the critical angle.
C. Glass to air: Total internal reflection can occur here if the angle of incidence exceeds the critical angle.
D. Glass into water: Total internal reflection can occur here if the angle of incidence exceeds the critical angle.
The correct answer is therefore none of the given options, as total internal reflection can potentially occur in all scenarios if the angle of incidence exceeds the critical angle.
