Reflection

Diffraction

Dispersion

Refraction

Angle of incidence > Angle of Reflection

Angle of incidence < Angle of Reflection

Angle of incidence = Angle of Reflection

No relation between Angle of incidence and Angle of Reflection

1/u - 1/v = 1/f

1/v – 1/u = 1/f

1/v + 1/u = 1/f

1/vu = 1/f
