Question

If the glancing angle of a incidence is 30 what os the angle of reflection?​

Answer 1

Answer:

60

Explanation:

glancing angle of incidence is 30

so angle of incidence = 90 - 30

                                    = 60

angle of incidence = angle of reflection

So,  angle of reflection = 60

Answer 2

90 -30

60 is the correct answer
