SUMMARY

The discussion clarifies the distinction between back silvered and front silvered mirrors, specifically in the context of optics. A back silvered mirror is created by depositing a reflective layer on the rear surface of a glass sheet, while a front silvered mirror has the reflective layer applied to the front surface. The choice between these types is critical for applications such as Lloyd's single mirror experiment, where front silvered mirrors are preferred to avoid double reflection, which occurs in back silvered mirrors. Understanding these differences is essential for anyone working with optical devices.

PREREQUISITES
  • Basic knowledge of optics and reflection principles
  • Familiarity with mirror manufacturing techniques
  • Understanding of image formation in concave and convex mirrors
  • Knowledge of Lloyd's single mirror experiment
NEXT STEPS
  • Research the process of creating front silvered mirrors
  • Study the optical properties of concave versus convex mirrors
  • Explore the applications of front silvered mirrors in scientific experiments
  • Learn about the impact of double reflection in optical systems
USEFUL FOR

Optics students, optical engineers, and professionals involved in mirror manufacturing or experimental physics will benefit from this discussion.

Homework Statement



Still I could not make the exact difference between the back silvered and the front silvered mirror. In many web sites only the method of making a back silvered mirror is given.
My doubt is-"what makes the deposit back silvered or front silvered?". How will you say that this surface of a transparent glass sheet is a front one and the other is the back one? After depositing the silver on anyone surface of a glass and place it upside down will it not become a back silvered one and if you keep it in the upright position will not the same act as a front silvered one? Please don't laugh at my question as it may sound trivial to the professional experts in the field of optics. Will anyone enlighten me on this question?

Instead of saying the back silvered and the front silvered mirror, you can say the convex surface silvered and the concave surface silvered mirror. In each case nature of the image formation is different.
 
Thank you for your reply. But your reply has not answered my question. I actually talk about plane glass mirrors. It is said that for ordinary domestic purpose a back silvered mirror is sufficient where as for experiments such as Lloyd's single mirror experiment, we have to use a front silvered mirror because in a back silvered mirror double reflection occurs. My doubt is about "how to make a front silvered one?"
