The below figure shows us the diagram of divergent and convergent beam of light.
Divergent/ parallel beam of light: The rays from a distant light source (such as the sun) are parallel to each other and they constitute a parallel beam. The rays tend to proceed away from a point.
Convergent beam: rays proceed towards a particular point.
