Question

convergance of light and divergence of light difference​

Answer 1

Convergence of light and divergence of light:

Convergence of light:

• When light rays meet at a single point.
• To concentrate light at a point of a convergent beam of light is used.
• Convergent beams rays do not spread and follow the same path.
• A parallel beam of light converges on passing through a convex lens.
• Beams converge in both concave and convex lens.
• Eg: Doctors use this type of beam to concentrate on teeth, ears, and eyes; solar devices.

Divergence of light:

• When the light rays from the same point source are spread away from each other.
• To spread light from the source, the diverging beam is used.
• A parallel beam of light diverges on passing through a concave lens.
• Beam diverges in both concave and convex lens.
• Eg: Street lights, table lamps.
