The instrument used to view stars is the

1. Analyze the question

The question asks for the specific optical instrument designed for observing distant objects, specifically celestial bodies like stars.

2. Explain the concept

Optical instruments are devices that use lenses or mirrors to manipulate light. To choose the right one, we must consider the purpose of each:

• Microscope: Used to magnify very small, nearby objects (like cells or bacteria).
• Film Projector: Used to project images from a film onto a screen for viewing.
• Prism Binoculars: Used for viewing distant terrestrial objects (like birds or scenery), but they are not powerful enough for deep space observation.
• Telescope: Specifically designed to collect light from distant objects (like stars and planets) and bring them into focus, making them appear larger and brighter.

3. Show the solution

• Step 1: Evaluate the nature of stars. Stars are extremely distant, meaning they appear as tiny points of light to the naked eye.
• Step 2: Identify the requirement. To see stars clearly, an instrument needs a large aperture (to collect as much light as possible) and a high magnification power.
• Step 3: Match the requirement to the options. A telescope is the only instrument listed that is engineered to gather light from vast distances in space.

4. Identify the answer

Comparing the options, the Telescope is the correct instrument for viewing stars.

5. Tip

Think of the prefixes: "Micro-" means small (for small things), while "Tele-" comes from the Greek word meaning "far off" (for things far away). This simple trick will help you distinguish between a microscope and a telescope every time!
