Object distance is 3 and image distance Is 12 find magnification |
|
Answer» Magnification:It is the action of magnifying something.It is the RATIO of the image distance(v) to the object distance(u).It is given by -v/u.Given:We have been given that the object distance(u) of an object is 3CM and its image distance(v) is 12cm.To Find:We need to find the magnification. Solution:We KNOW that magnification is given by:-v/u. Substituting the given values we have,magnification(m) = -v/u= -12/3= -4As the magnification is -4 which is NEGATIVE, this means that the image is inverted.Hence the magnification is -4. |
