Refractive Index Units - What Units are Used to Measure Refractive Index?

Click For Summary
SUMMARY

The refractive index of a medium is a dimensionless quantity, meaning it does not have any units. It is defined as the ratio of the speed of light in a vacuum to the speed of light in the medium. This concept is crucial for understanding optical properties and is essential for lab reports in physics and engineering. The refractive index can also be derived from the ratio of wavelengths or the sine of angles in Snell's Law.

PREREQUISITES
  • Understanding of basic optics concepts
  • Familiarity with Snell's Law
  • Knowledge of wave properties of light
  • Basic principles of physics related to light propagation

Refractive Index Units - URGENT -

Homework Statement



Does the Refractive Index of a medium have units. If so what are they? i am needing this for a lab report - so i can quote answers and feel fine that i am not giving any units. I am pretty sure there arent any.

No they do not have units as they are a ratio of velocities or wavelengths or sine's of angles.
 
thanks
