The optical instrument which is suitable for viewing a nearby objects is ………..?

Analysis

The question asks for the specific optical instrument designed to magnify and view objects that are very close to the observer (nearby objects).

Concept Explanation

Optical instruments are designed to manipulate light to help us see things more clearly. To determine the correct answer, let’s look at the function of each option:

• Telescope: Designed to view distant objects (like stars or planets) by gathering light and bringing the image closer.
• Sextant: A navigational instrument used to measure the angular distance between two visible objects, primarily used for celestial navigation.
• Microscope: Specifically designed to produce magnified images of very small, nearby objects that are otherwise invisible to the naked eye.
• Periscope: Used to see over or around obstacles (like looking out of a submarine or over a wall) by using mirrors or prisms to reflect light.

Step-by-Step Solution

1. Evaluate the requirement: We need an instrument for "nearby objects."
2. Eliminate options: • A (Telescope) is for distant objects. • B (Sextant) is for navigation/measurement. • D (Periscope) is for viewing around obstacles, not necessarily for magnifying nearby objects.
3. Identify the fit: A microscope uses a combination of lenses to magnify tiny, nearby specimens, making it the standard instrument for this purpose.

Conclusion

The microscope is the optical instrument specifically engineered to view and magnify nearby objects that are too small to be seen clearly by the human eye.

Exam Tip: Always remember the "Distance Rule": Telescopes are for Things far away (T-T), while Microscopes are for Minute (small/nearby) things (M-M).
