Study of light with mirrors, lenses, telescopes, prisms

Lines perpendicular to light's wavefronts

In straight lines

Reflection, absorption, transmission

$\theta_i = \theta_r$

Line perpendicular to surface where light hits

Angle between incident ray and normal

Absorb some wavelengths, reflect others we see

Transparent: light passes through; Opaque: blocks light
