Question

by giving reason state ur observation when a parallel beam of white light:
1)is passed through a hypo solution and then focous on a white screen
2)is passed through a hypo solution (to which few drops of sulphuric acid is added)and then focused on a white screen

Answer 1

Q1)  Hypo solution acts like a convex lens and forms a real inverted image. 

Q2) Sulfur particles reflect and scatter light rays.  However, Sodium sulfate also acts as convex lens but of less refractive index.
      Thus a real image is formed a little more distance away. There will be dots also in the image. These are shadows of Sulfur particles.
