i) Magnification
6. What do you infer from the experiment which you did to measure the object distance and
image distance? (AS)
h) Image distance​

Answer 1

Answer:

1) if obeject is b/w focus and center of curvature then image forms behind the center of curvature

2) a convex mirror has

• has +ve focus
• forms virtual images
• image is always erect
• has opque pant at concave side
• is diverging mirror

b concave mirror has

• -ve focus
• forms real images
• image is inverted
• covering mirror
• has opque paint at convex side

3) real image | virtual images

|

allways inverted | allways erect

|

can be obtained. | can't be obtained

on screen. | on screen

|

fromed by | formed by diverging

converging ray. | ray

4) see attached image

5)see attached image

I) magnification:- it is ratio of hight of image to the hight of object or H2/H1

j) image distance :- distance between mirror and image it's +ve when virtual image -ve when real image

object distance :- distance b/w object and mirror +ve in case of real object ie infront of mirror and -ve in terms of virtual object which is pace behind the mirror

6) I couldn't understand. sorry

hope it helps you
