Question

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

Answer 1

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

As ray of incidence makes a angle of 90 degree with the reflected ray ,angle of incidence=90/2 =45 degree.

Answer 2

Answer:

the ray of incidence will be 45°

Explanation:

As the angle between incident ray and reflected ray is 90°. And angle of incidence= angle of reflection.
