Question

Q5. A ray of light is incident on a plane mirror and the angle of reflection is 45
degrees. What is the angle between the incident ray and the reflected ray?
A. 45 degrees
B. 50degrees
C. 90 degrees
D. 100 degrees
​

Answer 1

Answer:

the angle between incident ray and reflected ray is 90 degree

Explanation:

we can give the full explanation of this question by using the law of reflection.

there are two law of reflection

i) incident ray , reflected ray and normal lies on same plane

ii)angle of incident = angle of reflection .

by using second law

angle of incident=45°

so angle of reflection =45°

therefore angle between them is 45°+45°=90°
