Chapter 10: The Relativistic Doppler Effect
10.1 Introduction to the Relativistic Doppler Effect The Doppler effect is the change in frequency and wavelength of a wave in relation to an observer who is moving relative to the wave source. In the context of special relativity, the Doppler effect plays an important role in the analysis of the behavior of electromagnetic waves,…

Longitudinal Waves
Introduction Longitudinal waves are a type of wave in which the displacement of the medium’s particles is parallel to the propagation of the wave. They are characterized by alternating regions of compressions (areas where the particles are close together) and rarefactions (areas where the particles are far apart). Wave Parameters and Properties Wave Speed The…

Doppler Effect
Introduction The Doppler Effect is a change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It is named after the Austrian physicist Christian Doppler, who proposed it in 1842. Basic Formulas The Doppler Effect can be described by the following formulas. For waves,…

Sound Waves
Introduction Sound waves are mechanical waves that propagate through a medium (like air, water, or solids) as a result of vibrations, creating pressure variations that the human ear detects as sound. They are longitudinal waves, where the oscillations occur in the direction of wave propagation. Speed of Sound The speed of sound varies depending on…
