Associated tutorial questions (St Andrews only)

• What is an image?
• How can an image be formed? :- pinhole camera, lens, (mirrors covered later)
• What shape does the lens need to be?
• Interactive demo of a converging lens bringing rays from one point all together again at another - the image.   From Lightlink
• Interactive demo of  a diverging lens  forming a virtual image.  From Lightlink
• Raytracing and focal length of a lens

Not part of our course, but of potential interest, is the use of satellites to image the earth.   I find it amazing the amount of detail that can now be seen from above the atmosphere. 

Similar material to that presented in the lectures is available at:-

• Halliday, Resnick, & Walker - Chapters on:-  Images
• University of Rochester - Reflection and Refraction at spherical surfaces
