• Tipler 34-27

• Snell's law practice
• conceptual

• Tipler 34-84

• Microscope, compound thin lens system
• Remember: image of the first lens becomes the object of the second lens.

• Tipler 34-70

• Simple geometry, use arclength = r*(theta) equation.
• This is a very real problem for very real eyes, should promote some interesting discussion.
• How far away can you see the two eyes of a fly as separate?
• What is the smallest angular separation of stars the normal human eye can resolve?
