Physics 20 - Nov 15

Today we looked at a very specific application of lenses, the eye.  We learned how the lens in the eye accommodates to the fact that objects that the eye sees are located at different distances, therefore the images will be located distances.  In the eye, this can't happen.  The eye cannot change the distance to the image (all images have to form on the retina), therefore it changes the shape of the lens to accommodate this fact.  This is called lens accommodation.  Slides 47-53 were taken up in the notes powerpoint.  Homework 3.6 was assigned and will be taken up on Tuesday.

On Monday we will be doing Lab 3.3 - Sheep Eye Dissection.
