SUMMARY

Mirrors reflect light completely, achieving 100% reflection and 0% refraction. In contrast, lenses exhibit both reflection and refraction properties, reflecting approximately 4% of light upon entry and another 4% upon exit, while refracting around 92% of the light. This distinction between the behavior of mirrors and lenses is crucial for understanding optical principles.

PREREQUISITES
  • Understanding of basic optics principles
  • Familiarity with light behavior in different mediums
  • Knowledge of reflection and refraction concepts
  • Basic physics terminology related to optics
NEXT STEPS
  • Research the laws of reflection and refraction in detail
  • Explore the differences between concave and convex lenses
  • Study the applications of mirrors and lenses in optical devices
  • Learn about the Fresnel equations for reflection and transmission
USEFUL FOR

Students of physics, optical engineers, and anyone interested in the principles of light behavior in mirrors and lenses.

Lenses reflect and refract. Mirrors reflect 100% and refract 0%. If my memory serves me, lenses well reflect ~4% when the light is on the way in, and another ~4% when light is on the way out. and the rest ~92% will refract.
