Question

explain with an experiment that light travels in straight line​

Answer 1

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 ...

Answer 2

This experiment is also know as the proof of the rectilinear propagation of light which means that light travels in straight line.

• We required opaque pages, cardboard holder, and a candle
• Then we put the three opaque pages on cardboard holder in straight line and put candle at starting of the line with burning candle.
• When we see that light travels from tell but put something between the opaque pages like cardboard we see than light is not reaching the other page.
• Which means light travels in straight line.
