LIGHT
LIGHT-light is the form of energy.which helps us to see the things.
REFLECTION-the bouncing back of light from the plane surface is called reflection.
TYPE OF REFLECTION
1.REGULAR REFLECTION
2.IRREGULAR REFLECTION
1.REGULAR REFLECTION-When light reflect from plane and smooth surface and reflected
in one direction and form a clear image.
2.IRREGULAR REFLECTION-Whan the light reflect from rough and irregular surface and
reflected in diffirent direction is called irregular reflection.
LAWS OF REFLECTION
1.Angle of reflection is always equal to angle of incident.
2.Incident rey,Reflected ray,Normal all lays on same place at'O'.
TYPE OF IMAGE
1.REAL IMAGE
2.VIRTUAL IMAGE
1.REAL IMAGE-A image that can brought on screen real image.
2.VIRTUAL IMAGE-A image thet can not brought on the screen is called virtual image.
DISPERSION OF LIGHT- A process in which the white light splite in seven different
colour.
that colour are:-
VIBGYOR
1.V=Violet
2.I=Indigo
3.B=Blue
4.G=Green
5.Y=Yellow
6.O=Orange
7.R=Red
NOTE:-1.Red have more wavelength so it is visibal from long distance.
2.Violet has less wavelength so it is not visibal from long distance.
3.The series of colour is according to its wavelength.
CHARACTERISTICS OF PLANE MIRRORS.
1.The image is formed behind the mirror.
2.The image that is made virtual,erectand laterally inverted.
3.The image the formed is as for behind the mirroras the object in the frount of
the mirror.
THE HUMAN EYE
WEIGHT OF HUMAN EYE
7-8gram
Size of human eye
24cm=24mm
Lens that is in human eye
Convex lens
