Question

Two identical thin isosceles prisms of refracting angle ‘A’ and refractive index m are placed with their bases touching each other Two parallel rays of light are incident on this system as shown The distance of the point where the rays converge from the prism is

  1. fraction numerator h over denominator mu A end fraction    
  2. fraction numerator h over denominator A end fraction    
  3. fraction numerator h over denominator left parenthesis mu minus left parenthesis A right parenthesis A end fraction    
  4. fraction numerator mu h over denominator left parenthesis mu minus left parenthesis A right parenthesis A end fraction    

The correct answer is: fraction numerator h over denominator left parenthesis mu minus left parenthesis A right parenthesis A end fraction
