Effects of deviation on every day light .....

The value of the deviation, discovered by Bradley, is small when the speed of a mobile is small as compared to the light speed. But when you change this ratio towards 1 (v=c), you can observe strange optical phenomenons that SR did not accept because of a pursueing ray. These following examples will convince you the other way.


For this purpose, I use a graphic software called Cabri Géomètre II Plus that you can download (for a free version) at www.cabri.com.


Where to download Cabri Géomètre II Plus ?

Once installed, download the following fig files (the files with extension fig are files created under Cabri software) :

The deviation (first observed by Bradley) is a relativistic effect on the path of a light ray that goes across a mobile. This document shows how to represent this deviation with Cabri Géomètre. You can change the mobile speed thus the ratio v/c or the source position relative to the target to see the variation of the deviation.
In this example, you can manipulate the objects to see the deviation effect in relation to the position of the source and the mobile speed under Cabri Java.

Let's see how the deviation behaves for different values of mobile speed.

How does a light beam reflect in a spherical mobile ? Einstein stated that the ray will go always through the center. In my opinion, the relativistic deviation will make the beam to follow different paths in relation with the mobile speed or the position of the source.

Do you still agree with Einstein?


How long will be Einstein's shadow if his bike goes as fast as the light ?



Does SR need to be reviewed ?
