Question

The image formed by a compound microscope is real, inverted and magnified. (State whether true or false)
(A) True
(B) False

Answer 1

Hint: To answer our question, we will first see the definition and working principle of a compound microscope. A compound microscope is an optical instrument which uses the visible lens and a set or sets of lens to magnify a tiny object. The basic difference between these and simple microscopes is that these are practically used for very high magnifications (100X-5000X).

Complete answer:
We will now see the working principle of a compound microscope and their image properties and then try to answer our question.
A compound microscope uses two step magnification, that is, at first the light from the object is incident on the objective lens of the microscope. Now, the magnification of any lens has an upper limit. So, this lens magnifies the image 8X-10X times. This first image is real and inverted.
Now, this real image acts as an object for the second lens. Here, more than one lens can be co-joint together to increase the total magnification of the object by thousands of times. The final image formed by these sets of lenses, including the eye-piece is virtual and inverted.
So, we can conclude that the final image formed by a compound microscope is enlarged, virtual and inverted in nature.
Hence, the statement, the image formed by a compound microscope is real, inverted and magnified is false.

Hence, option (B) is the correct option.

Note:
The property of image formed under different conditions, be it a microscope, lens or mirror should always be remembered thoroughly. These combined cover a major portion of one of the most important topics of Physics, that is Optics. In easy questions like these, one should not waste time on drawing a diagram and then finding out the nature of the image formed.
