sides are interchanged, the image
does not appear upside down.
types of mirrors
plane mirror
convex mirrors
concave mirrors
It can either be real or virtual.
It can either be inverted or erect.
It can have the same
size as that of the
object, a larger size
that of the object or
smaller size than that
of the object.
Satellite dishes , Dentists use a

It is always virtual.
It is always upright .
It is smaller in size as that of the object
The rear view
mirrors are convex
mirrors as they
provide a wider view
of the road behind.
types of lenses
concave lenses
convex lenses
A Convex Lens is curved outwards. It is
thicker in the centre and narrows down at the
edges. It merges the light rays passing
through it at a certain point. Therefore, it is
also called a Converging Lens.
real, inverted ,the image is
large when close to the lens
A Concave Lens is curved
inwards. It has wider edges
and a thinner centre. It
reflects back the light that
travels through it in
different directions.
Therefore, it is also called a
Diverging Lens.
virtual ,erect ,small
A lens is a part of a
reflecting material like glass
or plastic but curved from
both sides
reflection of light
refraction of light
dispersion of
light
splitting white light
into a spectrum of
colors after passing through different mediums
bending of light
after touching two
mediums
Light falls on the
surface of an object
and the object
sends the light back.
