Summary
We did not really do a project with optics, but we did learn about them. We learned how optics are used in everyday life, such as in lenses, or why the sky is blue, and why things seem bigger under water.
Concepts
The light spectrum is all the colors that human eye can see. It is a group of the waves that reach our planet. The light spectrum makes up the colors that we see. However, don't get confused; when you see a green object, it means that green is the only light wave being reflected, all the others are absorbed.
Reflection- Reflection occurs when light hits a surface that causes the light to bounce back. Light always bounces back at the same angle it hit the surface, as long as the surface it smooth.

Refraction- Refraction occurs when light changes medium(what is is traveling through) and therefore changes its direction. For example, when light goes from air to water the water is denser. This causes the light to bend at a different angle.
Lenses- Lenses are prisms that use refraction to converge or diverge light. Lenses are very hard to explain wit words so these diagrams are going to do the explaining.
Reflection
For me, optics were the hardest part of physics. Lenses especially can be very confusing. With all the mind hurting science we learned, I also learned some valuable lessons. I learned that sometimes you just need to take a breath and try to look at something different. Optics can confuse someone really easily and while you might want to get stressed out, you should try to take a deep breath and try to think about the problem in a different way.
