**Light refracts when it passes from one medium to another.

​Least bent = red

**Light refracts when it passes from one medium to another.

​Least bent = red

Violet

• shortest ​wavelength (in visible light) = slowed more = most bent

• ​higher index of refraction

**Light refracts when it passes from one medium to another.

​Least bent = red

Violet

• shortest ​wavelength (in visible light) = slowed more = most bent

• ​higher index of refraction

​Red

• longest wavelength (in visible light) ​= slowed a little = least bent

• ​lower index of refraction

​What is dispersion?

• the phenomenon when the different wavelengths of light are bent at slightly different angles when light is refracted
