Reflection of Light
Ray, Reflected ray, Normal, Angle of incidence, Angle of refraction,
Real Image, Virtual Image, Lateral Inversion
Spherical mirrors Concave, Convex ray diagrams
The mirror formula
1/f = 1/u + 1/v or
m = Height of image/ Height of object

Refraction of Light
Refractive index, Snells Law, Real and Apparent Depth
n = Sin i / Sin r
n = Real Depth/ Apparent Depth
Total internal reflection
1n2 = Sin i / Sin r = Sin C
2n1 = 1 / Sin C
Lenses
Principal axis, Principal focus, Focal plane, Focal length, Radius of curvature, Concave & Convex
Ray diagrams
Lens formula -
1/f = 1/u + 1/v
M = v/u = Height of image / Height of object
