Answer»

aim :To show that light travels in a STRAIGHT line

materials required: a candle ,a opaque tube

,a table

procedure: Light the candle and PLACE it on the table.Keeping an eye closed see the candle through the tube.note your observations.Now,give a LITTLE BENT to the tube and try to see the candle through the tube.

observation: The candle could be SEEN through the straight tube but when the tube was given a little bent the candle was not seen through the tube.

conclusion: This phenomena is thus proved and also known as rectilinear propagation of light

hope it helps

plz mark as brainliest ...
