Metal platings on glass and reflection in a mirror

Click For Summary

Discussion Overview

The discussion revolves around the effectiveness of various metal platings on glass in achieving maximum reflection as a mirror. Participants explore the conditions under which reflections may appear brighter or darker than the actual image and inquire about the absorption properties of different metals used for plating.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants inquire about which metal platings can provide 100% reflection as a mirror.
  • Questions are raised regarding the conditions that lead to a brighter or darker image compared to the actual one in a mirror.
  • There is a discussion about which metals used for coatings absorb the least amount of light, affecting their reflective properties.
  • One participant notes that every metal used for coating absorbs some light, preventing 100% reflection, and seeks to identify which metal offers maximum reflection.
  • Another participant suggests that it is beneficial to conduct preliminary reading on mirror surfaces and reflection before asking specific questions.

Areas of Agreement / Disagreement

Participants express varying levels of understanding and knowledge about the topic, with no consensus on specific metals or conditions for achieving maximum reflection. The discussion remains unresolved regarding the optimal materials and their properties.

Contextual Notes

Participants reference the need for further reading to clarify their questions, indicating that their understanding may depend on additional information not yet discussed in the thread.

Which metal platings on glass will provide 100% reflection as a mirror?
In which case we will get an brighter image than the actual one in mirror?And in which case it will be darker?Which metal(used for platings) will absorb a very little amount of ray? Can anyone give the explanation?

What reading have you been doing so far about mirror surfaces and reflection? Can you post some links to that reading, and ask specific questions about which parts you don't understand? :smile:

I didn't read anything about it recently.I just thought about it.
I heard that every metal(which is used for coating) absorbs some ray,thats why they can't give 100% reflection.So,I want to know which metal can give maximum reflection?And do the coating have any impact on image?

It's always best here at the PF to do some reading first, and then ask specific questions about your reading if you don't understand something. That's a good way to learn about new things. Especially with the Internet, it is easy to find good articles to do initial reading. Have a look at this Wikipedia article to see if it is a good starting point to learn more about how reflection works:
