The distance between object and the screen is D . Real images of an object are formed on the screen two positions of a lens seperated by a distance d. What will be the ratio between the sizes of two images?

PhysicsGeneral

  1. D squared over d squared
  2. D over d
  3. square root of straight D over straight d end root
  4. fraction numerator open parentheses D minus d squared close parentheses over denominator left parenthesis D plus d right parenthesis squared end fraction

    Answer:The correct answer is: fraction numerator open parentheses D minus d squared close parentheses over denominator left parenthesis D plus d right parenthesis squared end fraction
