Journal Entry 9/21

A.

  • "We are able to see because light from an object can move through space and reach our eyes".
  • This is wrong because light does not move directly from a luminous object to your eye, it is reflected off a surface.
  • I know that an light rays must be reflected off of a surface in order to be seen as a result of the extensive work we did with laser beams. When a laser beam is shot at the wall, the only reason I can see it is because rays within that beam are reflecting off of the wall. If this wasn't the case, I would be able to see the light of the beam in between the laser emitter and the wall.
  • If this sentence said, "We are able to see becasue light from an object moves through space, reflects off some surface, and then reaches our eyes", it would be accurate.

I studied the article for about an hour, but I couldn't find anything else wrong with it. Could you give me a hint Mr. D'Amato?

This is good Nicole thank you.

Can you find another part of the article that would be confusing to someone who did not understand the lesson as well as you did? What if someone was trying to figure this out without doing all the experiments we did?

Please make a NEW POST titled "Journal entry 9/21 continued" and complete the assignment.
