Lens

A
35
Q

Lens is a transparent

A
36
Q

material made of glass or

A
37
Q

plastic that refracts light

A
38
Q

rays and focuses (or

A
39
Q

appear to focus) them at

A
40
Q

a point.

Q

CONVEX LENS

A
42
Q

• It is thicker in the center than edges.

A
43
Q

• It forms real imnages and virtual

A
44
Q

images depending on position of the

A
45
Q

object. In very distant object

A

it gives

46
Q

an inverted image.

A
47
Q

•It is also called Converging Lens

A
48
Q

because the light that passes through

A
49
Q

it tends to converge at a particular

A
50
Q

point called the focal point.

Q

• It is thicker at the edges and thinner

A

Q

•It forms upright and reduced images.

A

Q

•It is also called Diverging Lens

A

Q

because the light that passes
