When a photon leaves the air and enters a denser medium at an angle, the flight path of the photon changes direction. A fish at the bottom of a pool is deeper than it appears, and in the same manner, light that enters glass at an angle is deflected. This is depicted in the following illustration.
A photon changes its flight path because its elastic strings are ejected at 90 degrees to its line of flight. Those strings that penetrate the glass will cause the photon to pivot and change their flight direction. A photon is not a simple wave oriented in just one plane; it is more like a fuzz ball with respect to its strings, which means more often than not elastic strings will penetrate the glass and cause it to pivot. The same considerations apply when the photon exits glass, only now the strings cause the photon to return to its original line of flight.
Visible white light from our Sun is composed of photons of many different frequencies. When this light is passed through a prism, it reveals the true composition of the light. Scientists have shown that blue light bends more when going through a glass prism than red light. This is shown in the following illustration.
Red light has the lowest oscillation frequency of all visible light, while blue light has one of the highest with almost twice the frequency of red light. This means at that critical point when light first enters the prism, photons that make up blue light create anchor points faster than red photons. On average blue photons will be curving twice as soon as the red photons, which will cause the separation of photons of different frequency.
In the next blog, we will see how elastic strings explain reinforcement and interference. Till then be safe and in good health. Kelland—www.vestheory.com
