A teaching tape for SR-09, Doppler and aberration

doppler aberration

Teaching tape demonstrating the relativistic Doppler effect and aberration under a 0.6c boost.

Open SR-09 with these settings

Where it starts

The settings the tape begins from, under the constant set modern-si-2019. Values are the model's own, not the laboratory control's display: a radius of 5e-7 is half a micrometre.
SettingValue
Observer frame speed (beta)0.6
Propagation angle (propagationAngleDeg)0
Wave frequency (frequencyTHz)500

What it changes, and what to expect

  1. Set Observer frame speed (beta) to 0.6 describes the same world from somewhere else

    doppler-aberration-0.6

    At 0.6c receding light along the axis halves its frequency (factor 0.5) while phase remains invariant.

These are the values the tape's author recorded, not a result this page computed. Nothing here runs the instrument. Open SR-09 with these settings: the link opens it with them already in place. Compare what it gives you with what is recorded here. The settings travel in the link and the laboratory reads them as it loads, so without JavaScript it opens at its worked example instead.
