Is photon gravity lensing affected by frequency (energy)?

Click For Summary
SUMMARY

The discussion centers on whether photon gravity lensing is influenced by the frequency (energy) of photons. It is established that gravitational lensing is not affected by the frequency of light; all photons, regardless of their energy, experience the same degree of deflection when passing near massive objects like black holes. The misconception that higher energy photons would be deflected more due to increased mass is clarified, emphasizing that deflection in gravitational lensing is independent of photon mass and momentum. The principle of gravitational lensing applies uniformly to all light, aligning with Newtonian gravity principles.

PREREQUISITES
  • Understanding of basic physics concepts, particularly gravitational lensing.
  • Familiarity with the equation E=mc² and its implications.
  • Knowledge of Newtonian gravity and its application to massive objects.
  • Basic comprehension of the wave-particle duality of light.
NEXT STEPS
  • Research the principles of gravitational lensing in astrophysics.
  • Study the relationship between energy, frequency, and wavelength of photons.
  • Explore the effects of mass and momentum in classical mechanics.
  • Learn about the implications of Einstein's theory of relativity on light behavior near massive objects.
USEFUL FOR

Astronomy enthusiasts, physics students, and anyone interested in understanding the behavior of light in gravitational fields will benefit from this discussion.

Homework Statement


I am NOT a student. Please forgive my asking here, but if you do choose to answer, I would appreciate it.

Obviously any or all of the statements below may be incorrect...

As I understand it:
The more energy a photon has (I know it's also a wave) the greater the frequency.
Energy = mass (not necessarily matter obviously)
The more mass the more a photon would be deflected (let's say by passing by a black hole)
Is gravitational lensing affected by frequency?

Homework Equations


E=MC^2 comes to mind.

The Attempt at a Solution


I'm stumped. (I realize that not saying much).
Perhaps, just as all weights fall at the same rate (Barring air resistance) they deflect to the same degree?
Perhaps mass and momentum should be treated separately? Because I'm conflating resistance to turning as mass having momentum?That you for your insight. I apologize for disturbing the forum.

This is not true.

No. Deflection is the same for all light. There is no need to consider relativistic effects to understand this: the same is true to normal massive objects in Newtonian gravity: deflection depends on the speed, but not on the mass.

Thank you. I just wondered, and I didn't know enough (any) physics to answer the question myself.
