Question

Two identical thin isosceles prisms of refracting angle ‘A’ and refractive index mu 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 1 right parenthesis A end fraction    
  4. fraction numerator mu h over denominator left parenthesis mu minus 1 right parenthesis A end fraction    

The correct answer is: fraction numerator h over denominator left parenthesis mu minus 1 right parenthesis A end fraction

A concave mirror is placed on a horizontal surface and two thin uniform layers of different transparent liquids (which do not mix or interact) are formed on the reflecting surface. The refractive indices of the upper and lower liquids are mu subscript 1 end subscript and mu subscript 2 end subscript respectively. The bright point source at a height ‘d’ (d is very large in comparison to the thickness of the film) above the mirror coincides with its own final image. The radius of curvature of the reflecting surface therefore is
