Directions : In the following questions, A statement of Assertion (A)...
Magnification of microscope is inversely proportional to focal lengths of objective lens and the eyepiece lens. Hence both the focal lengths are small. On the other hand, magnification of microscope is inversely proportional to focal lengths of eyepiece lens and directly proportional to the objective lens. So, the focal length of the objective lens is large and the focal length of the eyepiece lens is small.

Hence, if the objective lens and the eyepiece lens of a microscope are interchanged that will not meet the criterion of the telescope.
So, the reason is true. But the assertion is false.

Directions : In the following questions, A statement of Assertion (A)...
Assertion: If the objective lens and the eyepiece lens of a microscope are interchanged, it works as a telescope.
Reason: Objective lens of telescope require large focal length and eyepiece lens require small focal length.
The correct answer is option D, which states that Assertion (A) is false and Reason (R) is true.
Explanation:
A microscope and a telescope are two different optical instruments used for different purposes. However, they both consist of lenses that perform different functions. Let's analyze the given assertion and reason to understand why the answer is option D.
Interchanging Objective and Eyepiece Lenses:
When the objective lens and the eyepiece lens of a microscope are interchanged, it does not work as a telescope. This is because the lenses in a microscope are specifically designed and optimized for magnifying small objects at close range, while the lenses in a telescope are designed for observing distant objects.
Objective Lens and Eyepiece Lens Requirements:
The assertion mentions that the objective lens of a telescope requires a large focal length, while the eyepiece lens requires a small focal length. This statement is true.
Objective Lens:
The objective lens in a telescope is responsible for collecting and focusing light from distant objects. It needs to have a large focal length in order to gather as much light as possible and provide a clear and magnified image.
Eyepiece Lens:
The eyepiece lens in a telescope is used to further magnify the image formed by the objective lens and bring it to the viewer's eye. It requires a smaller focal length to achieve the desired magnification.
Conclusion:
In conclusion, interchanging the objective and eyepiece lenses of a microscope does not result in a functioning telescope. The objective lens and eyepiece lens of a telescope are designed differently and have specific requirements in terms of focal length. While the objective lens of a telescope requires a large focal length, the eyepiece lens requires a small focal length. Therefore, the given assertion is false, and the reason provided is true.
Reason: Objective lens of telescope require large focal length and eyepiece lens require small focal length.
The correct answer is option D, which states that Assertion (A) is false and Reason (R) is true.
