Ritz effect, Doppler effect, binary radio pulsar
Translated to English with Google Translate by Thomas E. Miles
According to ballistic theory, an accelerated source at each subsequent moment imparts a slightly different speed to the light, and successive signals (or fronts of light waves) emitted at different speeds catch up with each other (reducing the wavelength), or diverge (increasing the wavelength), arriving at the receiver more or less often. From the transformation of the time intervals dt and the period T, we find for the change in the wavelength λ = cT, the frequency of light f = 1/T, - new intervals, wavelengths and frequencies, respectively...
Effect (1), which complements the Doppler effect, will further be called the Ritz effect...
