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

  • Physics -

    angle of incidence = 30o

    angle of reflection = 60o



    angle between incident ray and reflected ray = 120o

  • Physics -

    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
