This is the diagram of formation of rainbow due to dispersion of light. 

i. Dispersion occurs at the point ‘A’ because the splitting of colours of white light occurs at this point. 

ii. Internal reflection occurs at the point(s) B and B’ because the light gets divided into several colours or beams and gets reflected.
