Discussion Overview

The discussion revolves around the behavior of light when it interacts with a lens, specifically focusing on reflection and the conditions under which light may or may not propagate through the lens. The scope includes theoretical aspects of optics and the implications of total internal reflection.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants assert that light will reflect off the surface of a lens, with the amount of reflection depending on the angle of incidence and the presence of anti-reflection coatings.
  • One participant inquires about the propagation of light through a lens during total internal reflection, seeking clarification on whether any light reaches the other side.
  • Another participant responds that total internal reflection results in no light propagating to the other side of the lens, stating that it is "total."

Areas of Agreement / Disagreement

There is a disagreement regarding the implications of total internal reflection, with one participant questioning the propagation of light while another asserts that none propagates under those conditions.

When a passing through a lens,will there any reflection on the surface of it?

Absolutely. The amount of light reflected from the surface depends on the angle of incidence along with other factors such as whether the lens has any anti-reflection coatings or not.

Thanks.And I want to ask if there any light propagate to the other side of the lens when total internal reflection occurs?

No. Total reflection really is total
