LIGHT -

 LIGHT IS A FORM OF ENERGY WHICH ENABLE US TO SEE ANY THING.

NATURE OF LIGHT 

1) IT IS ELECTROMAGNETIC WAVE(EM) WAVES AND DO NOT REQUIRED ANY MEDIUM      FOR THEIR PROPAGATION.

2) WAVELENGTH OF VISIBLE LIGHT  ( VIBGYOR ) IS VERY SMALL .

3) SPEED OF LIGHT IS VERY HIGH.(3*10^8 M/S).

4) IT IS C0MPOSED OF PARTICLES, WHICH TRAVES IN A STRAIGHT LINE.

REFLECTION OF LIGHT 

WHEN THE LIGHT IS ALLOWED TO FALL ON HIGHLY POLISHED SURFACE , SUCH AS MIRROR, MOST OS THE LIGHT GET REFLECTED IN THE SAME MEDIUM.

FIRST LAW /SECOND LOW

1)ANGLE OF INCIDENCE =ANGLE OF REFLATION.

2) THE INCIDENT RAY, REFLECTED RAY, AMD NORMAL AT THE POINT OF INCIDENCE,      OF THE  REFLECTING SURFACE LIE IN THE SAME PLANE.
