Question

What is the difference between divergent beam and convergent beam

Answer 1

Light rays from a point source of light travel in all directions, moving away with time. Such a beam of light is called a divergent beam of light. A convergent beam of light rays comes together (converges) after reflection and refraction at a single point known as the focus.

Answer 2

divergent beam is the beam which gets enter into the prism and is diverged to other side while converged beam is a beam which does not gets diverged
here the word diverged means to go into another direction
