Question

Choose the correct statement regarding a compound microscope being used to look at a mite.

The eyepiece lens forms a real image of the mite.

The converging objective lens forms a virtual image of the mite.

The eyepiece lens forms a virtual image of the mite.

If the focal distance of the objective lens is shortened, then its magnification decreases.

The mite should be located at the focal point of the objective lens.

Answer 1

Answer : The following statement is correct statement regarding a compound microscope being used to look at a mite :

• The eyepiece lens forms a virtual image of the mite.

The eyepiece lens forms a virtual image of the mite for which the real image formed by the converging objective lens will act as object. The eyepiece is placed such that the image formed by the objective falls at first focal point of the eyepiece.

The objective lens produces a real image of the object, by having the object be just beyond its focal length and the eyepiece will then be placed very close to the image, so that the image falls within the eyepiece’s focal length and it produces Virtual, inverted and enlarged image.
