1
Q
how are images formed
A
1 .refelction
2. refraction
2
Q
where are images formed
A
wherever two or more reflected/refracted light rays intersect each other
3
Q
types of images
A
- real
- virtual
4
Q
charateristics of real image
A
- image is inverted w.r.t. the obj
- image can be captured on a screen
when two or more refelcted/refracted light actually intersect each other
5
Q
virtual image
A
when two or more refelcted/refracted light appear to intersect each other
6
Q
guide to make ray diagram
A
- where is obj
- where is img
- nature of img (virtual/real, upright/inverted, size of img compared to obj)
show arrows
