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
