<span><span>-When sunlight strikes a falling drop of water it is refracted, changed indirection, by the surface of the water.</span>
The light continues into the drop and is reflected from the back of the drop to the front. When the beam hits the front it is refracted again and emerges from the drop as the color spectrum that we see in a rainbow.<span>-The water drop acts like a prism to seperate the light into its different wave lengths.</span></span>

Work, in physics, is the force exerted or applied in order to move an object to a certain distance. It is calculated from the product of force and the distance. It is the energy that is transferred during the movement. It will have units of N-m which is equivalent to J, a unit of energy. We calculate as follows:
Work = Force x distance
Work = 20 N x 2 m
Work = 40 N-m or 40 J
