Question
In which of the following two arrangements (a) and (b) shown in the diagram, you can see the light of the bulb? Explain Your answer
Short Note
Solution
We can see the light of the bulb in the arrangement (a).
This is so because in arrangement ‘a’ the rod is straight and light travels in a straight-line path.
Whereas in arrangement ‘b’ the rod is bent. So the light cannot pass through it.
