2 image and dim calc

On page three of Issue 3 Winter-Spring 86/87, there is a picture of a

resonant cavity. What is thelikely diameter?

Quick Analysis

For this analysis, it was determined that glare line on the cylinder basically was midline of the housing. The diameter of the tube is likely the same as Stan's other tubes. The outside dimension is likely to be 5.5 inches, possibly 6.

********

Since the sphere wil be placed in the center of the tube, the edges of the cylinder as rendered in 2d will be the same distance from the observer as the center of the sphere, If the cycinder is assumed to be 5.5 inches in outer diameter then the ratio of the diameter of the sphere to the tube diameter will give a rough idea of the sphere diameter.
