Question

draw a labelled diagram of an experiment to show rectilinear propagation of light​
​

Answer 1

Answer:

Explanation:

➡️Take three cardboards A, B and C and make a pinhole at their centers.

➡️Place a burning candle on one side of A and arrange the cardboards in such a way that the three pinholes and the candle flame are in a straight line.

➡️ The candle flame will be visible through the pinhole of the cardboard C.

➡️Now slightly displace any one of the cardboards and try to see the flame through the pinhole of the cardboard C.

➡️ The flame will not be visible.

➡️From this it is clear that light travels in a straight line.
