Core practical: Investigating refraction (Edexcel GCSE Physics): Flashcards

Light changes direction between media due to speed change

Air: low; Glass: higher

Towards the normal

Away from the normal

Produces narrow beam of light

Line perpendicular ($90°$) to surface

Angle between incident ray and normal

Angle between refracted ray and normal

Angle between emergent ray and normal at exit

Less than angle of incidence

Higher optical density than air

All electromagnetic waves

Greater refraction
