An object is placed at a distance of 48 cm in front of a concave mirror of focal length 24 cm.
(i) Find the position of image formed.
(ii) What will be the nature of image?
Answers
Answer:
The image is at a distance of 48 cm from the mirror. As the magnification is negative , the image formed is real , inverted.
Since the image is formed in front of the concave mirror, its nature will be “Real and Inverted”. To find the size of image, we will have to calculate the magnification first.
...
(iii) Size of image.
The magnification produced by a mirror is given by :
m = v/u
m = h2/h1
Here, Magnification,m = −4 (Found above)
Mirror formula is relationship that combines image distance ,object distance and focal length of the mirror . Here u=object distance as measured from pole of the mirror and V=image distance and f being the focal length of the mirror.
