Oops, the bunny has disappeared, so I'll blog for today's class. Everyone needed to hand in Waves in 2D assignment 1. We covered the math for Snell's law and saw how the law was derived. The ratio of the wavelengths, speeds, and sines can give the value for the index of refraction, n. This value is just a ratio which means it doesn't have any units. The index of refraction, n, is specific for each type of material (water, glass).
The assignment for the weekend is to complete problems 5-8 at the end of the green booklet. If you're thinking you should realize that question #6 is a repeat of the question we did on the whiteboard.
Remember your 1 page assignment is due on Tuesday. Have a great weekend.
Oh yeah, the scribe for Monday will be
