- A photon is a single light particle that cannot be divided under normal circumstances, but it lacks a specific location and is an extended object.
- If a mirror is suddenly removed while a photon is reflecting, the outcome is more complex than expected, according to Norwegian physicists.
- Photons can divide or combine only under nonlinear conditions, such as when the medium changes in response to light, typically requiring a sensitive medium or high-intensity laser.
- The sudden removal of a mirror during photon reflection is considered a nonlinear event, though it may not align with typical linear thinking about photon-mirror interactions.
