Question

The ray diagram could be correct

  1. If n subscript 1 end subscript equals n subscript 2 end subscript equals n subscript g end subscript    
  2. If n subscript 1 end subscript equals n subscript 2 end subscript and n subscript 1 end subscript less than n subscript g end subscript    
  3. If n subscript 1 end subscript equals n subscript 2 end subscript and n subscript 1 end subscript greater than n subscript g end subscript    
  4. Under no circumstances    

The correct answer is: If n subscript 1 end subscript equals n subscript 2 end subscript and n subscript 1 end subscript greater than n subscript g end subscript


    If n subscript l end subscript greater than n subscript g end subscript then the lens will be in more denser medium. Hence its nature will change and the convex lens will behave like a concave lens.
