Question

if the angle of incidence on a plane mirror is 90degrees the angles of reflection is? ​

Answer 1

Answer:

90°

Explanation:

Given That

Incident angle = 90°

Incident angle = Reflected Angle

SO, 90° = 90°

Answer 2

Answer:

90 degrees

Explanation:

angle of incidence =angle of reflection

so angle I =angle r

90=90
