Journal Entry 9/28 continued

1. Constant motion does not afford time for a light ray to reflect. When the pond is calm, it acts as a mirror for the rays to reflect off of, but when the water is moving, it is shifting as it is reflecting. Therefore, the reflected rays are being absorbed into the motion of the water, and fail to produce a picture of the landscape.

2. The portion of the spoon that is under water refracts light rays that hit it. Three-quarters of the spoon are underwater so a lot of rays are being refracted. When the refracted rays are all concentrated towards one area, that is the area where the image appears.

1. This is an interesting idea, well described, but it's not necessary to introduce a new idea in order to explain this observation with the concept of reflection.

Reflection still occurs when the surface of the lake is disturbed, so why is there no image?

2. The essence of your explanation is close enough to what I am looking for! Eyes see the image where the light rays come from. When they are refracted it looks like they are coming from somewhere else.

Finish the lake explanation in a new entry please.
