Question

A symmetrical biconcave lens having radius of curvature R is made up of two different materials as shown in figure. A parallel beam of light passing through the lens appear to diverge from two different points. Find the distance between them.

  1. fraction numerator 2 over denominator R end fraction open parentheses mu subscript 1 end subscript minus mu subscript 2 end subscript close parentheses    
  2. fraction numerator R over denominator 2 end fraction fraction numerator open parentheses mu subscript 2 end subscript minus mu subscript 1 end subscript close parentheses over denominator open parentheses mu subscript 1 end subscript minus 1 close parentheses open parentheses mu subscript 2 end subscript minus 1 close parentheses end fraction    
  3. fraction numerator R over denominator 2 end fraction open parentheses fraction numerator mu subscript 2 end subscript minus 1 over denominator mu subscript 1 end subscript minus 1 end fraction close parentheses    
  4. fraction numerator R over denominator 2 end fraction open parentheses fraction numerator mu subscript 1 end subscript minus 1 over denominator mu subscript 2 end subscript minus 1 end fraction close parentheses    

The correct answer is: fraction numerator R over denominator 2 end fraction open parentheses fraction numerator mu subscript 1 end subscript minus 1 over denominator mu subscript 2 end subscript minus 1 end fraction close parentheses
