In the current physics textbooks, only one formula is given for the Doppler effect of light in vacuum, however there is actually another one. In this paper, the two formulas are derived based on the quantum and wave properties of light, and their consistency is analyzed. Then finally the ...
Similarly, for light waves, the doppler effect accounts for the change in frequency or wavelength of light as a result of relative motion between the source of light and the observer. The doppler effect has applications in various fields, including astronomy (determining the movement of stars and...
In summary, the Doppler effect refers to the change in frequency or wavelength of a wave due to relative motion, Doppler shift is the specific term for the resulting change in frequency, and Doppler expansion is the redshift of light from distant celestial objects caused by the expansion of t...
A formula is derived for the combined motional and gravitational Doppler effect in general stationary axisymmetric metrics for a photon emitted parallel or antiparallel to the assumed circular orbital motion of its source. The same formula is derived fro
The greater the motion toward or away from us, the greater the Doppler shift. If the relative motion is entirely along the line of sight, the formula for the Doppler shift of light isΔλλ=vcΔλλ=vcwhere λ is the wavelength emitted by the source, Δλ is the difference between λ...
Doppler Effect In Light Doppler effect of light can be described as the apparent change in the frequency of the light observed by the observer due to relative motion between the source of light and the observer. For sound waves, however, the equations for the Doppler shift differ markedly depe...
TheDoppler effectalso occurs for light. However, the Doppler effect of starlight is different from that of sound, because the velocity of the light is constant and the time dilation occurs in thespecial relativitytheory. The Doppler effect of light is expressed as: ...
Moving Point Light SourceDoppler EffectEinstein's Doppler formula is not applicable when a moving point light source is close enough to the observer; for example, it may break down or cannot specify a determinate value when the point source and the observer overlap. In this paper, Doppler ...
