Question

Which of the following statements is not true if an incident ray of light makes an angle of 30o with the mirror surface?


angle of incidence = 30o

angle of reflection = 60o

angle of incidence = 60o

angle between incident ray and reflected ray = 120o

Answer 1

angle of incidence = 30o

angle of reflection = 60o



angle between incident ray and reflected ray = 120o

Answer 2

we know angle of incidence(i)=angle of reflection(v)
given, The angle between incident ray and reflected ray is 120⁰
given, i+v=120⁰
we know i=v
hence i=v=120degree /2
