5/8 Physics Class and homework due 5/15

Hi folks,

Today we spent a bit of time really trying to fully understand these lenses and ray diagrams. We also worked with the behavior of convex and concave mirrors and learned how to draw ray diagrams for them.

Homework for next week is to:

1. Draw a ray diagram for a convex mirror. Put the location of the object farther than the focal point.

2. Draw a ray diagram for a concave mirror. Put the location of the object between the focal point and the mirror.

. Draw a ray diagram for a concave mirror. Put the location of the object farther than the focal point.

4. Draw a ray diagram for a concave lens. Put the location of the object where ever you'd like.

5.  Draw 3 ray diagrams for a convex lens. For each diagram, move the location of the object.  Do two diagrams with the object between the focal point and the lens and 1 with the object beyond the focal point.  Please use a ruler to create your rays.

Once you do these, I HIGHLY recommend doing some of these a second time before next Monday.  There will be a quiz on all of these so please try to master this.

Here is a great website that does a nice job explaining how to do these.  Feel free to refer to these if you need to.
