In case of displacement method of lenses, the product of magnification in both cases is

Lenses,Displacement Method

What is the magnification in this case ?

Displacement method||Examples on lenses

Roasting results in the production of metal in the case of :

How do a combination of lenses helps in higher magnification?

Assertion: In displacement method of finding focal length of a convex lens its magnification in one position of lens is +2, then magnification in another position of lens should be -1/2. Reason:This method can't be applied for a concave lens.
