Dispersion (VCE SSCE Physics): Flashcards

White light separates into colours in a medium

Different wavelengths have different refractive indices

Shorter wavelengths have higher refractive indices

Violet bends more than red

Colours focus at different points, causing blurred images

Hot below, inverted image appears below object

Lower than cool air

Core (high $n$) and cladding (low $n$)

One reflection; red top, violet bottom

Two reflections; violet top, red bottom; fainter
