Plot a graph of angle of incidence, i in o on the y-axis against angle of refraction, r in o on the x-axis and draw the line of best fit. We can see from the graph that as the angle of incidence, i, ...

WXMI — In our science experiment today, we look at a disappearing coin trick, which really is no trick at all. It illustrates density and refraction. Some things are more dense (or heavier) than other ...

To investigate the reflection of light by different types of surface, and the refraction of light by different substances. Remove the block. Join the crosses to show the paths of the light rays ...

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...

Explains the concept of light traveling in straight lines and demonstrates this through various experiments. It shows how light can be observed through holes in cards, how it behaves in a lightproof ...
