The formula that doesn't feature mass of the attracted/bended object you marked as "GR". - This answer made me realize that bending does, in fact, not depend of the mass, thus not on the wavelength of the photon. That is impressive. | |

| May 18, 2022 at 5:12 | comment | added | JLA | You can't show this within the framework of classical mechanics though, as far as I see. You can compute the acceleration due to gravity with nonzero mass and take the limit as $m\to 0\,,$ however in doing this you seem to get a contradiction with Newton's first law which states that an object can't change directions unless a nonzero force acts on it. | |
| May 18, 2022 at 4:23 | comment | added | John Rennie | @JLA no this applies to massless particles as well. The acceleration of an object in a gravitational field is independent of the mass even when the mass is zero. | |
| May 18, 2022 at 1:54 | comment | added | JLA | Doesn't the Newtonian prediction depend on the photon having mass though? Otherwise it violates Newton's first law. | |
