Question

what is the angle of incidence of a ray if the reflected ray is at the angle of 90 to the incidence ray ... who will be able to tell me first , will be mrk brainliest..​

Answer 1

$\large\mathbb{SOLUTION}}$

Since the angle of reflection=Angle of incidence,

as stated the angle of reflected Ray is 90°

so angle of reflection is 45°

So angle of incidence would also be 45
