Light – Reflection and
Refraction
Laws of Reflection
The angle of incidence is equal to the angle of reflection.
The incident ray, the normal to the mirror at the point of incidence and the reflected ray, all lie in the same plane.
Laws of Refraction
The ratio of the sine of the angle of incidence i to the sine of the angle of refraction r is constant for the pair of given media
The incident ray, the refracted ray and the normal at the point of incidence, all lie in the same plane.
Parts of a Mirror
Pole (P)
Center of Curvature (C)
Radius (R)
Principal Axis
Principal Focus
Aperture
Parts of a Lens
Optical Center (O)
Principal Axis

Pole
Aperture
Sign Convention
The Pole is taken as the Origin
Any distance from perpendicular to the pole upwards is taken is positive
Any distance from the left of the pole is taken is negaitive
Any distance from perpendicular to the pole downwards is taken is negative
Any distance from the right of the pole is taken is positive
