Describing Wave Motion (OCR GCSE Physics A (Gateway Science Suite)): Flashcards

Refract, reflect, or be absorbed

$\text{angle of incidence} = \text{angle of reflection}$

Angle between incoming wave and normal line

Angle between reflected wave and normal line

Line perpendicular to the boundary

Waves bounce off smooth surface, reflect at same angle

Clear, shiny reflection (like a mirror)

Waves hit rough surface, reflect at different angles

Matte surface without clear reflection

When a wave crosses from one material to another at an angle

Away from the normal

Toward the normal

Slower

Faster
