Answer:According to the law of reflection, the angle of incidence is equal to the angle of refraction.

That is, ∠i=∠r. Let it be x.

In this case, the difference between the angle of incidence and angle of refraction is 90 degrees.

Given, ∠i+∠r = 90 degrees

or, x+x=90  

0

 

or,  x=45  

0

 

Hence, the angle of incidence is 45  

0
