WebThe following equation is used to calculate redshift: \ [z=\frac {\lambda observed-\lambda rest} {\lambda rest}\] So if a distant galaxy emits a characteristic spectral line of 91 nm... Webwhere z is the gravitational redshift, G is Newton’s gravitational constant, M is the mass of the object, r is the photon’s starting distance from M, and c is the speed of light. In this case, the gravitational redshift suffered by a photon emitted from the star’s surface is a tiny 3 × 10 …

Gravitational Redshift -- from Eric Weisstein

WebRedshift Wavelength Redshift happens when light or other electromagnetic radiation from an object is increased in wavelength, or shifted to the red end of the spectrum. The … WebDefine the redshift = z by the equation (&lambda denotes wavelength) z = (&lambda observed - &lambda lab)/&lambda lab. This is defined so that if the object is moving away from us, the observed wavelength will be longer than expected and z will be positive. From the Doppler shift formula, the velocity of the galaxy is v = c z .
