CONTENT

Light is travelled by straight line.Light cannot bend along the tube.Light travels in a straight line known as

rectilinear propagation of light.

LIGHT

• It is one of the unique properties of light.• The bouncing back of rays of light from a

polished and shiny surface is reflection of light.

REFLECTION OF LIGHT

The light ray , which strikes any surface is incident ray.

The ray that comes back from the surface after reflection is reflected ray.

Make an angle 90 to the line represently the mirror at the point where the incident ray strikes the mirror is normal line.

REFLECTION OF LIGHT

The angle of incidence is the angle between normal and incident ray.

The angle of reflection is the angle between the normal and reflected ray.

Angle of incidence is always equal to the angle of reflection .This is Laws of reflection.

LAW OF REFLECTION

i=angle of incidencer=angle of reflected rayLaw of reflection Angle of incidence=angle of reflected

ray i = r

Figure representation of law of reflection

An image formed by a mirror the left of the object appears on the right and the right appears on the left, This is Lateral inversion.

LATERAL INVERSION

When all parallel rays reflected from a plane surface are not parallel, the reflection is Irregular reflection.

It is otherwise known as Diffused reflection.

IRREGULAR REFLECTION

Reflection from a smooth surface like that of as mirror is called Regular reflection.

REGULAR REFLECTION
