Speed of light in denser and rarer medium.

Click For Summary
SUMMARY

The speed of light is constant for all observers only in a vacuum. In denser and rarer media, the speed of light varies, leading to the phenomenon of refraction. This fundamental principle is crucial for understanding optical physics and the behavior of light in different materials.

PREREQUISITES
  • Understanding of basic optics concepts
  • Familiarity with the principles of refraction
  • Knowledge of the speed of light in a vacuum
  • Basic physics of wave propagation
NEXT STEPS
  • Research the principles of Snell's Law in optics
  • Explore the effects of different media on light speed
  • Study the implications of light speed in various materials
  • Learn about the applications of refraction in optical devices
USEFUL FOR

Students of physics, optical engineers, and anyone interested in the behavior of light in different media.

I was studying refraction and as I've heard and read, it occurs due to difference between speed of light in the rarer and denser medium. But isn't speed of light common for all observers? Please don't make fun of me if I've made a stupid mistake somewhere.

Yes, but only in a vacuum.
 
Oh. Thank you for the answer.
