Answer 2

Answer:

Fix a lighted candle on a table.take a rubber tube,stretch it straight and look through it at the flame of the candle with the 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. now,bend the rubber tube.so after do than we can observe we can not able to see the light of candle. this means that the light of candle flame can travel through the straigh rubber tube but not through the bend rubber tube. from this observation we conclude that light travel in straigh lines
