Answer: Pls mark as brainlest and thank my answer than your all wishes will come true
Explanation: Take a torch. Cover its glass with a chart
paper which has three narrow slits as
shown in Fig. 15.5. Spread a sheet of at a lighted candle first through
a straight pipe and then through
a bent pipe (Fig. 15.2). Why was
Boojho not able to see the candle
flame through a bent pipe?
This activity showed that
light travels along straight lines.
How can we change the path
of light? Do you know, what
happens when light falls on a
polished or a shiny surface?
