concept question
Concept Question

Suppose the sprinters wish to get from point Q on the beach to point P on the parking lot as quickly as possible. Which path takes the least time?

  • a
  • b
  • c
  • d
  • e
  • All paths take the same amount of time.
index of refraction
Index of Refraction

Going from one medium to another, the frequency of light does not change but its wavelength does.

If one of the medium’s is vacuum (n=1),

Snell’s Law of Refraction

  • Cell phones on silent.
  • Fermat’s principle: nothing quantitative– just understand the idea of minimum time.

View From a Fish Eye

For q<qc: The fish sees above the water

For q=qc : The fish sees the shoreline

For q>qc : The fish sees the pond bottom
