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.
