The magnification produced by a plane mirror is Fl. What does it mean?
5. An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. find
the position and nature of the image.
Answers
Answer:
we can find the position of image by calculating the image distance, v.
Here, Object distcance, u = - 10 cm (To the left of mirror)
Image distance, v = ? (To be calculated )
And, Focal length, f = + 15 cm (It is a convex mirror)
Putting these values in the mirror formula :
1v+1u=1f
We get: 1v+1−10=115
1v−110=115
1v=115+110
1v=2+330
1v=530
1v=16
So, Image distance, v = + 6 cm
Thus, the position of image is at a distance of 6 cm from the convex mirror on its right side (behind the mirror). Since the image is formed behind the convex mirror, therefore, the nature of image is virtual and erect.
Explanation:
Hope it will help you!
The magnification produced by a plane mirror is +1 means that the image formed is virtual, erect and of the same size as that of object.
