Unformatted text preview: es Doppler Shift for E&M Waves What’s Different from Sound or Water Waves ? Sound /Water Waves : You can calculate (no relativity needed) BUT Result is somewhat complicated: is source or observer moving wrt medium? Electromagnetic Waves : You need relativity (time dilation) to calculate BUT Result is simple: only depends on relative motion of source & observer 1 2 1+ β f′= f ÷ 1− β β = v/c v/c β > 0 if source & observer are approaching if source & observer are approaching β < 0 if source & observer are separating if source & observer are separating Doppler Shift for E&M Waves Doppler Shift for E&M Waves f f’ v or f f’ v The Doppler Shift is the SAME for b...
