Expert Answer:

Convergence is the physical joining together of light rays. Light rays tend to come together at a point (called point of convergence) from different directions.
Light rays on reflecting on concave mirror converges at focus or point of converegence. 
This phenomenon of convergence is used in following examples: - 
  • Dentists use concave mirrors to view large images of the teeth of the patients.
  • Large concave mirrors are used to concentrate sunlight in order to produce heat in the solar furnaces
