Q

Orientation

32
Q

Size

A

can be reduced, magnified, or the same as the object

33
Q

Type

A

can either be real or virtual

34
Q

First, a simple outline of the lens is drawn with a horizontal axis passing through the middle of it or the principal axis.

A
35
Q

The positions of the focuses F, with equal distances from the lens, on both sides of the lens was marked.

A
36
Q

The first ray was drawn parallel to the axis from the top of the object to the lens and deflected down towards the focal point. This is known as the principal ray.

A
37
Q

The second ray is drawn passing through the focal point to the lens. This ray is then deflected through the lens in a direction parallel to the principal axis. This is known as the focal ray.

A
38
Q

The third ray was drawn straight from the top of the arrow (the object) through the middle of the lens without deflection. This is also known as the central ray.

A
39
Q

The image is formed at the point where the three rays intersect.

Q

42
Q

_ are lenses that thin at the middle and bulk at the edges.

A

Diverging lenses

43
Q

These are also known as _.

Diverging lenses

A

concave lenses

44
Q

There are different kinds of diverging lenses, the most common is the _ _.

A

biconcave lens

45
Q

Diverging lenses deflect _ rays away from each other, making it appear as if
they diverge from the focal point

A

parallel

46
Q

The first ray is parallel to the principal axis of the diverging lens which will refract through the lens and travel in line with the focal point. This is known as the principal ray.

A
47
Q

The second ray, the focal ray, passes towards the focus at the opposite side and will refract through the lens and travel parallel to the principal axis.

A
48
Q

The third ray passes through the center of the lens is unrefracted, this is the central ray. It directly passes through the center without being bent.

A
49
Q

The intersection of the extensions of the rays determines the location and characteristics of the image formed by the diverging lens.
