Write one activity to show that light travels in straight line and gets reflected in mirror.

Dear Student,

Take 30 cm long pipe having small diameter of the cross section and place a candle at one end of the pipe. Now look through the other and of the pipe. You can see the candle.Now bend the pipe and look through the same end,  at this time candle is not visible. This shows that the light travels in a straight line. 


​Regards
