Question

Is it possible that though the ray of light is entering a denser media but still angle of refraction is greater than angle of incidence?

Answer 1

Answer:

The only way for the angle of refraction to be greater than the angle of incidence is for light to bend away from the normal. Since light only bends away from the normal when passing from a more dense medium into a less dense medium, then this would be a necessary condition for total internal reflection.
