Question

What is the angle of incidence of a ray if the reflected Ray is at an angle of 90° to the incident Ray ?​

Answer 1

Answer:

angle of incidence= 45°

angle of incidence=angle of reflection....=x

Explanation:

2x=90

x=45°

Answer 2

Answer:

angle of incidence is equals to 45 degree and angle of incidence is equals to angle of reflection so angle of incidence is equals to angle of reflection is equals to X so 2 X is equals to 90 degree and X is equals to 45 degree
