Formulas and Key Relations

2. Spherical Mirrors

R = 2f

Mirror formula: 1/v + 1/u = 1/f

Magnification (mirror): m = h'/h = -v/u

4. Refraction of Light

Snell's law: sin i / sin r = constant

n21 = v1 / v2

n12 = v2 / v1

Absolute refractive index: n_m = c / v

Key relations

For spherical mirrors of small aperture, the radius of curvature is twice the focal length, so R = 2f.
