Telescope | MCQs

Explanation

Distant objects can be seen with the help of the Telescope

They produce an image that is larger than the image that can be seen with the unaided eye.

Telescopes gather far more light than the eye,

It allows dim objects to be observed with greater magnification and better resolution.

Explanation

A reflecting telescope uses two mirrors:

1. The primary mirror (which collects and focuses light).
2. The secondary mirror (which directs the focused light to the eyepiece), to form an image of distant objects.

Explanation

When Galileo pointed his telescope at Jupiter, the largest planet in our solar system, he made a startling discovery.

The planet had four "stars" surrounding it.

Explanation

A telescope is used by the eye to see distant objects. Similarly:  A necklace is worn around the neck

Explanation

Galileo made his first telescope in 1609

The telescope is an optical instrument used to view distant objects/small object

Barometer Inventor: Evangelista Torricelli

Steam engine Inventor: Thomas Savery

Microscope Inventor : Zacharias Janssen

Explanation

Galileo was a natural philosopher, astronomer, and mathematician. He also made revolutionary telescopic discoveries, including the four largest moons of Jupiter.

Explanation

Telescopes are designed to collect and magnify light from distant objects, such as stars, planets, and galaxies.

They are ideal for viewing faint or dim objects in the night sky, as they can gather more light than the human eye alone.

Explanation

Telescope: It is a device used to see distant objects.

The word telescope was coined in 1611 by the Greek mathematician Giovanni Demisiani

Explanation

A refracting telescope has two lenses:

1. A primary lens (objective) that collects and focuses light.
2. A secondary lens (eyepiece) that magnifies the focused light to form an image.
