1.angle of incidence is equal to angle of refraction is equal to angle of emergence
2. Angle of incidence is equal to angle of emergence is greater than angle of refraction
3. Angle of incidence is equal to angle of emergence is lesser than angle of refraction

ANSWER:-
" OPTION C "
EXPLANATION:-
IN QUESTION IS GIVEN THAT LIGHT RAY IS GOING FROM AIR TO GLASS MEANS RARER TO DENSER. THEN, ANGLE OF INCIDENCE WILL BE EQUAL TO THE ANGLE OF EMERGENT AND
IT WILL LESS THAN ANGLE OF REFRACTION.
IT HAPPENS BECAUSE WHILE GOING FROM RARER TO DENSER THE RAY OF LIGHT REFRACTS TOWARDS THE NORMAL AND AT THAT TIME ANGLE OF INCIDENCE IS GREATER THAN ANGLE OF REFRACTION. AND WHILE GOING FROM DENSER TO RARER RAY OF LIGHT REFRACTS AWAY FROM THE NORMAL.
HENCE,
FROM ABOVE TWO PARAGRAPHS WE CAN SAY THAT "OPTION C" IS RIGHT.

Answer:
1 ) .
Both angles are equal to each others i.e. ∠i = ∠e.
2 ) .
Angle of emergence also increases.
3 ) .
The light ray falls along the normal or the refractive index of the two optical media are equal.
