### Optics B/C

I just realized this wasn't a thing..
So here goes.
Start simple (kind of):
The first medium is air and the second is water. The angle of incidence is 45 degrees. What is the angle of refraction?

(I hope I worded this correctly enough.)

Uh oh, I haven't done anything optics-related since my school's tryouts last year...
32.1 degrees?
Just trying my best...

Someone else can post a question if Ten086 doesn't post in the next 24 hours...

I'll post one.

A photon has wavelength 500 nm when traveling in crown glass (n=1.52). What is its color?

$f \times 5 \times 10^{-7} = \frac{3 \times 10^{8}}{1.52} \rightarrow \lambda_{real} = 760 \mathrm{nm}$

Oh jeez sorry, completely forgot that I replied in here Sorry, first time doing anything in a question marathon. This forum sure is dead though, is it just early in the year or are question marathons not very active?

In general, the physics events have not historically had very active question marathons. The main exceptions are Simple Machines 2015 and Optics last year, though neither were particularly long. Typically, all it takes is a few active people to keep a question marathon active - which is what happened in Simple Machines, a lot of it was mjcox2000 and I going back and forth with higher-level problems (well, higher-level for Div B).
