Homework Help Overview

The discussion revolves around the behavior of photons in the context of relativity, specifically addressing the question of what occurs when a photon is absorbed by an electron and the implications of a photon "coming to rest." The subject area is primarily focused on concepts from relativity and quantum mechanics.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the idea of whether a photon can truly come to rest and question the implications of relativity regarding the speed of light. There are discussions about the behavior of photons in different media, such as glass, and the interpretations of slowing down.

Discussion Status

The discussion is ongoing, with participants raising questions about the original poster's assumptions and providing references to additional resources. There is an exploration of different interpretations regarding the behavior of photons, but no consensus has been reached.

Contextual Notes

Some participants reference the theory of relativity and its implications for light speed, while others point out the behavior of photons in various materials, suggesting a need for clarification on definitions and assumptions regarding speed and absorption.

Homework Statement


according to theory of relativity anything which travels at the speed of light, can't be slowed down at the speed lower than light speed.So, what happens when photon is absorbed by an electron?In this situation photon comes to rest. How it can be explained?
