magnification of a mirror (m) is
Answers
Answer:
The magnification, m produced by a spherical mirror can be expressed as: m=h′h where h′ is height of image and h is height of object. It is also equal to the negative of the ratio of the image distance(v) to object distance (u).
Answer:
The magnification of a mirror gives a comparison between the height of the object and the height of the image formed.
Explanation:
The value of magnification of mirrors helps us to understand the type of image formed in it. We have 2 equations for the magnification. They are:
(1) m = h₁/h₀
Where h₁ is the height of the image and h₀ is the height of the object.
(2) m = -(v/u)
Where 'v' is the image distance and u is the object distance.
If the magnification is positive image formed is virtual and erect.
If the magnification is negative image formed is real and inverted.
If magnification is 1, the height of the image equals the height of the object.
If magnification is less than 1 image height is less than that of the object.
If magnification is greater than 1 image height is greater than that of the object.
