If a 20 cm tall rabbit is playing at a distance of 30 cm in front of a concave mirror attached to its cage. What will be its height in the mirror if the focal length is 16 cm ?
Answers
Answer:
The focal length of the mirror is 20cm.
In the case of real image,
The object distance is u
1
, then the image distance will be −2u
1
.
The mirror formula is given as,
v

u

In the case of virtual image,
The object distance is −u
2
, then the image distance will be 2u
2
.
The mirror formula is given as,
v

+
u

=10cm
The distance between two positions of object is given as,
u=30−10
=20cm
Thus the distance between the two positions of object is 20cm.
