A ray of light originates from inside a glass slab and is incident on

1.	A ray of light originates from inside a glass slab and is incident on its inner surface at an angle θ as shownIn this experiment the location x of the spot where the ray hits the screen is recorded. Which of the following correctly shows the plot of variation of x with the angle θ ?(A) A (B) B (C) C (D) D
Answer» Correct Option :- (A) A Explanation :- This is case of Total Internal Reflector (90– θ) is incident angle. As θ increases thus incident angle decreaes. Initially Ray will be Reflected at θ_C angle will be TIR after words Refraction takes place

Answer»

Correct Option :- (A) A

Explanation :-

This is case of Total Internal Reflector (90– θ) is incident angle. As θ increases thus incident angle decreaes. Initially Ray will be Reflected at θ_C angle will be TIR after words Refraction takes place
