    Explain Image Mirror
Click For Summary

Discussion Overview

The discussion revolves around the formation of images in a plane mirror, particularly focusing on the behavior of photons when they interact with objects and mirrors. Participants explore concepts related to light reflection, color perception, and the nature of image formation.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions whether photons carry the image with them or if they function like a camera when reflecting off objects.
  • Another participant explains that when a photon strikes an object, it can either be absorbed or reflected, suggesting that a red object reflects red photons while absorbing others, thus conveying color information.
  • A participant expresses doubt about why mirrors reflect all colored photons and questions whether mirrors absorb specific colored photons.
  • In response, it is noted that while mirrors generally reflect photons, all materials have specific frequencies they absorb.
  • Another contribution asserts that photons contain information about the object, but the human eye and brain are necessary to interpret this information, distinguishing between color, shape, and position.

Areas of Agreement / Disagreement

Participants express differing views on the nature of photons and their role in image formation, with no consensus reached on whether photons carry the image or how mirrors interact with different colors of light.

Contextual Notes

Some assumptions about the behavior of light and the properties of materials are not fully explored, and the discussion does not resolve the complexities of how images are formed or perceived.

how image is formed on a plane mirror , when light bulb is switched on, photon strikes a point on an object ( for ex.a ball) and from their the photon strikes the mirror and form incident angle and reflective angle , my question is does the photon carry the image with it ? or does it act like a camera ?
 
Science news on Phys.org
Two possibilities exist when the photon strikes the object:

1) it is absorbed
2) it is reflected

So a RED object will absorb all visible light except RED. The RED photon will be reflected off the object and will strike the mirror and be reflected into your eyecausing you to see a RED spot on the object. Other parts of the object are illuminated in a similar way. The photon carries a pixel of the image but not the whole image.
 
thanks for reply , i have a doubt , why mirror reflects all coloured photons?, doesn't mirror absorb some specific coloured protons ?
 
You can answer your own questions just by reading a little on wikipedia for example:

http://en.wikipedia.org/wiki/Mirror

Mirrors reflect photons in general but every material will absorb some specific frequencies.
 
my question is does the photon carry the image with it ? or does it act like a camera ?

The photons do contain all the information about the object but you need something like the eye of an observer to put it all together. Some properties like the colour of the object are conveyed differently to properties such as shape and position. The human eye and brain interprets the frequency of the photon as colour. Shape and position information is conveyed in the direction from which the photons arrive at the eye.
