Question

In most compound microscopes, which part provides the greatest magnifying function? ​

Answer 1

Answer:

The compound microscope has two systems of lenses for greater magnification, 1) the ocular, or eyepiece lens that one looks into and 2) the objective lens, or the lens closest to the object.

Answer 2

In most compound microscopes, the system of the objective lens and ocular lens provides the greatest magnifying function

Magnification in a compound microscope:

The magnification provided by the compound microscope is the product of the magnification of -

• objective lens
• eyepiece (ocular lens)

Power of the two lenses in a compound microscope:

Taking reciprocal of focal length in metres gives power in dioptres.

• Objective lens- The power of the objective lens is generally more, which is around 4X, 10X, or 40X.
• Eyepiece- Normally, the power of the eyepiece lens is less than that of the objective lens. It is mostly 10X.

Thus, greater magnification is provided by the objective lens.

However, both the lens combinedly gives the greatest magnifying function. For example, an eyepiece of 4X with an objective lens of 10X will give a magnification of 40X.
