Chapter 14, Problem 2TE

To determine

Whether it is possible to view an elliptical shaped rainbow, if a person moves sideways from the point of site of a circular arced rainbow.

Answer to Problem 2TE

A person cannot see an elliptical segment of a rainbow by moving sideways from the point of sight of a circular arced rainbow.

Explanation of Solution

A rainbow is produced due to the reflection and dispersion of sunlight inside water drops. A rainbow has a primary as well as a secondary bow.

The rainbow is in the form of a three-dimensional cone. A rainbow is seen as a circular arc because it is formed far away from our view.

The rainbow faces us squarely. If a person moves sideways, it feels like the rainbow also moves sideways. Our horizon is changed when a person moves from one position giving the view of a different rainbow. But, the shape of the rainbow does not change.

Conclusion:

Therefore, we cannot see an elliptical segment of a rainbow by moving sideways from the point of sight of a circular arced rainbow.
