A group of students took an old shoe box and covered it with a black paper from all sides. They fixed a source
of light (a torch) at one end of the box by making a hole in it and making another hole on the other side to view
the light. They placed a milk sample contained in a beaker/tumbler in the box, as shown in Figure. They were
amazed to see that milk taken in the tumbler was illuminated. They tried the same activity by taking a salt
solution but found that light simply passed through it.

A. Explain why the milk sample was illuminated. Name the phenomenon involved.

B. Same results were not observed with a salt solution. Explain.

C. Can you suggest two more solutions which would show the same effect as shown in the milk solution?

25. Give reason for the following questions:- 5
