Write a paragraph on the relativity test by bending of light
equation 2.12: (dr/d?)^2 + (1-(r*/r)) (l^2)/(r^2)= P^2esc= l^2/b^2
r^2 d/dlambda= l=bp_esc Write a paragraph on the relativity test by bending light. How does one proceed from equations of motion (2.10) and (2.11) to get an equation about the shape of the orbit. One does an expansion in powers of r*, respectively c^-2, which is a small parameter. What is the zeroth order term obtained with r* = 0. One puts r^-1 =: u = u_0 + u_1 + .... Which equation does one get for u_1. Which formula for light bending does one obtain?Explanation / Answer
According to general relativity, a light ray arriving from the left would be bent inwards such that its apparent direction of origin, when viewed from the right, would differ by an angle (, the deflection angle ) whose size is inversely proportional to the distance (d) of the closest approach of the ray path to the center of mass.
The deflection angle is largest when the light rays pass closest to the mass; becomes smaller as d becomes larger. For the Sun, the curves look similar, but the predicted value of is five thousand times smaller for rays that skim the surface of the Sun than for rays that skim the surface of this "pseudo" Sun.
One of the things that General Relativity predicts is that light will bend around a massive object (such as the Sun). Newtonian gravity also predicts this. However, General Relativity predicts that light will bend twice as much as the value predicted by Newtonian gravity. The first observation of light deflection was performed by noting the change in position of stars as they passed near the Sun on the celestial sphere. The observations were performed in May 1919 by Arthur Eddington and his collaborators during a total solar eclipse .
