Which statement is incorrect regarding the reflection of light?
(A) The incident ray and the reflected ray are on opposite sides of the normal. (B) If the angle of incidence is 900 then the reflected ray is emitted in the same direction.
(C) If the angle of incidence is 450 then the angle of reflection is 450 .
(D) If the angle of incidence is 350 then the angle of reflection is 550 .

Answer
Correct option is
D
100
o
The angle at which a ray is incident is same as the angle at which the rays gets reflected.
So, angle between the incident ray and the reflected ray= 2( angle of incidence)
=2×50
o
=100

Answer:
The correct answer is (D) If the angle of incidence is 35° then the angle of reflection is 55°.
Explanation:
We know that according to the law of reflection, the angle of reflection is always equal to the angle of incidence. This means if a light ray hits a smooth surface at an angle of 75°, the reflected angle will also be 75°.
If the angle of incidence is 35°, then the angle of reflection also has to be 35° according to the law of reflection.
Conclusion:
If the angle of incidence is 35° then the angle of reflection is 35° too.
