Re: Optics B/C
Lol apparently I'm bad at my own questions. I ran through it again and I got the same answer as Tom and Jon.

Not sure how far I should go with this, but I'll give a bit.jonboyage wrote:Briefly explain the phenomenon of tertiary rainbows
A tertiary rainbow is the term given to a rainbow produced by light leaving the drop after three reflections. It is generally less bright than one would expect, due to various factors such as glare from surrounding light, light that does not undergo reflection within the drop, etc. Another factor that makes it difficult to see is its angle in relation to the Sun - ~45°.

sunlight scatters off the molecules in the Earth's atmosphere (Rayleigh scattering). This scattering is effective at short wavelengths, thus the light scattering down is primarily blue.

I have two possible explanations: 1. The wave has entered a theoretical material with a refractive index of 0.5. 2. The wave manages to have an incredibly short period.
