Key Concepts

Wavelength Change in a Medium

When light enters a medium from another, its speed and wavelength change while its frequency remains constant. The new wavelength in the medium is calculated by dividing the original wavelength by the medium’s refractive index, which is critical when analyzing refraction phenomena.

Refractive Index

The refractive index is a dimensionless number that indicates how much light slows down in a medium compared to its speed in a vacuum. It is fundamental in determining how light changes direction and wavelength as it crosses the boundary between different media.
