**total magnification of a light microscope is achieved when**

The magnification is usually just the magnification of the objective times the magnification of the eyepiece.

Or do you mean what is the maximum magnification that can achieved with visible light? Which is about 1000 x

Or do you mean what light should be used to achieve the maximum magnification… blue light , shorter wavelength allows for larger magnification than red light.

The total magnification depends upon the power of the ocular times the power of the objective lens. So in a typical lab microscope you would likely find a 10X ocular and three or four objective lenses: 4X, 10X, 40X (45X in some scopes, and 100X. The total magnification for each of these would be 40X, 100X, 400X (450X), and 1000X. Some older scopes have 47X and 97X as objective lenses so those would be 470X and 970X.

If you need the total magnification for the microscope you used, you’ll have to get it from the microscope itself!

By multiplying the ocular lens (nearest your eye) strength and the objective lens (nearest the specimen ) strength. if ocular lens is 4x and objective lens is 10x then total magnification is 40x. hope this helps you

None of the above.

The definition of the magnification of a single lens is the eye near point divided by its focal length. This makes the objective magnification 250x and the eyepiece 25x. This results in a total of 6250x. The object distance is irrelevant.

However, the eye near point for these calculations is defined as 25cm not 50cm.

the total magnification is the magnification of the objective (10x/40x/100x usually, but can be something else) which is further magnified by the eye piece (typically 10x, but others exist).

so multiply the objective by the eye piece.

10 x 40 = 400x.
