Experiment to Show Light Travels in a Straight Line
Arrange the index cards so that light can be seen through all the holes. Here is a simple experiment to explain this. Science Experiment Light Travels In A Straight Line Think Stations Science Experiments Travel Light Experiments Pass a string through the holes and pull it. . Move any of the cardboards and observe what happens. Take a pin and make a small hole in each cardboard at the same height. Let us carry out a small activity to show that lightwave travels along a straight line. To show that light travels in straight line. Now take the string out. Now bend the rubber tube a little and look through it at the candle flame again see Figure b. This shows that light travels in a straight line. The path of light can be easily proved by putting an object on its path. A pinhole camera is a simple camera without a lens but with a tiny aperture a pinhole-effectively a tight proof box with a small hole in one si...
