Lesson 4

I feel the help of a sec4 presenter has helped Wilson a lot, but one thing for lewis to take not of that we have observed is the speed and content of the note-taking. Our group has found this a huge problem in our class, most including me. I type, along with other students, very slowly but we do try to type as fast as possible. Overall content was pretty good, and our group has already gone through a brief intro about their slides, and they just gone more in-depth.

Notes:

Reflection is the bending of light.

Light can exhibit both a wave theory and a particle theory at the same time.

When light is reflected from a flat and smooth mirror, it bounces off at the same angle in the opposite direction from where it hit.

Supposedly, light particles must always travel in straight lines. But light diffraction says otherwise.

Reflector telescopes are cheaper but need regular cleaning of mirrors.

The refractor telescope is more expensive initially but can produce better images. Compound telescopes are portable and easy to assemble and disassemble. But they have a narrower point of view.
