Question
Part I: Light Beams
In Part I(b), as you moved the focal point from 50 to 200 on the optical axis, the lens ---Select--- became fatter did not change shape became slimmer .
In Part I(c), the reason the colored rays are dispersed so that you can see individual colored rays is because the ---Select--- index of polarization index of reflection index of refraction is different for each color of the spectrum.
This phenomenon is referred to as ---Select--- immersion dispersion specular reflection of light.
