Ray

Ray diagrams allow us to investigate the properties of light. Drawing them correctly is an important scientific skill.

Draw a perfect ray diagram which fulfills the following criteria

• it is drawn using a protractor, ruler, pencil
• the mirror, prism or glass block is drawn correctly
• there are labelled normal lines at every interface (dashed)
• lines are plotted with crosses and completes with a straight lines
• arrows indicate the direction of light
• label the incident and reflected or refracted rays
• label the angles to the normal in degrees

Your diagram should perfectly demonstrate hat light travels in straight lines. No wobbles. No kinks.
