Rohan tries to view a burning candle flame through a straight rubber pipe and can see it clearly. However, when he bends the pipe into an 'S' shape, he can no longer see the flame. Which property of light does this activity demonstrate?
Light gets reflected inside bent surfaces.
Light travels only in straight lines.
Light gets converted into heat inside rubber pipes.
Light travels faster through air than through rubber.
Solution
Light travels in a straight line (rectilinear propagation), so bending the pipe blocks the straight path of light rays coming from the flame.
