Question

with the help of an activity, prove that light travels in a straight line.​

Answer 1

Answer:

Take a rubber tube, stretch it straight and look through it at the flame of the candle with one eye (keeping the other eye closed). We will find that when the rubber tube is straight, we can see the light of candle flame through it. ... From this observation we conclude that light travels in a straight line.l

Answer 2

AIM- TO SHOW THAT LIGHT TRAVRLS IN A STRAIT LINE

MATERIALS REQUIRED- CANDEL AND 3 CARDBOARDS

PROCEDURE-

TAKE 3 CARDBOARDS, MAKE A HOLE IN ALL OF THEM AND PUT THEM IN SUCH A WAY THAT THE HOLES APPEAR TO BE IN A STRAIT LINE. NOW LIGHT THE CANDIL AND KEEP IT INFRONT OF THE HOLES. NOW LOOK FROM THE OTHER END(KEEP ONE EYE CLOSED). YOU WILL BE ABLE TO SEE THE FLAME.

NOW DISPLACE ONE CARDBOARD(HOLES DO NOT APPEAR TO BE IN STRAIT LINE). NOW LOOK THROUGH THE HOLE, YOU WONT SEE THE FLAME OF LIGHT.

OBSERVARION- FLAME IS NOT VISIBLE WHEN CARDBOARD IS DISPLACED.

CONCLUSION- LIGHT TRAVELS IN A STRAIT LINE.
