Assertion (A): If the rays are diverging after emerging from a lens; the lens must be concave.  

Reason (R): The convex lens can give diverging rays.  




  • It is not necessary that if the rays are diverging after emerging from the lens then the lens is concave.
  • In Convex lens , if object is between O ptical Center and F ocus, the rays are diverging
  • If the rays crossing the focal point of the convex lens, become diverging.  
  • Therefore, lenses can be concave or convex. 



  • Assertion is false
  • Reasoning is true

So, the correct answer is (d)
