Chapter 23, Problem 13Q

To determine

To analyze:

How a round drop of transparent and colorless water on a table can be seen.

Answer to Problem 13Q

Solution:

If the round drop of transparent and colorless water on a surface has been viewed, portion of the tabletop seem to be raised up as the lightleaving the tabletop and going through the drop due to the refraction.

The light in the room reflect off the drop and the reflection can also be viewed.

Explanation of Solution

A round drop of transparent and color less water on a table has been viewed. The refraction and the reflection can be observed.

One reason you can see a drop of transparent and colorless water on a surface is refraction. The lightleaving the tabletop and going through the drop on the way to your eye will make that portion of the tabletop seem to be raised up, due to depth distortion and/or magnification due to the round drop.

Asecond reason that you can see the drop is reflection. At certain angles, the light sources in the roomwill reflect off of the drop and give its location away.
