What causes the gravitational redshift phenomenon?

Click For Summary

Discussion Overview

The discussion centers around the phenomenon of gravitational redshift, specifically questioning its applicability to different types of waves beyond electromagnetic radiation, and whether it is a result of gravitational time dilation. Participants explore the implications and definitions surrounding this concept.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant questions whether gravitational redshift is limited to electromagnetic waves, noting that other types of waves, such as sonic waves, do not exhibit this phenomenon.
  • Another participant asserts that gravitational redshift applies to all types of waves, attributing it to the effect of time moving more slowly in stronger gravitational fields.
  • A participant references a Wikipedia definition of gravitational redshift, seeking clarification on its applicability beyond electromagnetic radiation.
  • There is a request for clearer communication and understanding of the concepts involved, highlighting potential language barriers among participants.

Areas of Agreement / Disagreement

Participants express differing views on whether gravitational redshift is exclusive to electromagnetic waves, indicating that multiple competing perspectives remain unresolved.

Contextual Notes

Some participants exhibit uncertainty regarding the definitions and implications of gravitational redshift, and there are indications of language barriers affecting the clarity of the discussion.

The item of gravitational redshift in the WIKIpedia says that this redshift is referred to the light of others forms of electromagnetic waves. This puzzles me. Other waves except electromagnetic waves have not this phenomenon, like sonic wave ? Is the gravitational redshift a result of gravitational time dilation? Thx
 
Physics news on Phys.org
your english is incomprehensible. how about a quote from wikipedia
 
what is the meaning of the nost incomprihensive thing about the universe is that it is comprihensive give detail meanig of it
 
“In physics, light or other forms of electromagnetic radiation of a certain wavelength originating from a source placed in a region of stronger gravitational field (and which could be said to have climbed "uphill" out of a gravity well) will be found to be of longer wavelength when received by an observer in a region of weaker gravitational field.”

This is from the wikipedia. Sorry my English poor, so I can not express myself correctly.
I want to know whether the gravitational redshift is just about the electromagnetic waves?

Thx.
 
Gravitational redshift applies to all types of waves. Its the result of time moving more slowly deeper in a gravity well.
