To show that light travels in straight line.
To show that light travels in straight line.There are two experiments are used to demonstrate how light travels in straight lines. In the first example, the presenter arranges three pieces of card, with holes in, in an uneven line. The light stops and cannot travel through all three cards. When she arranges the holes in a straight line, the light can travel through. In the second example, a light source is shone onto a shiny and uneven surface. We see how the light still travels in a straight line, but scatters and reflects in different directions.
