Telescope

The video tutorial explains the basic types of telescopes, starting with refracting telescopes that use lenses to magnify distant objects. It then discusses reflecting telescopes, which use mirrors and can be built larger to observe dimmer objects.

What is the primary function of a telescope?

• To magnify and observe distant objects

• To create light

• To measure temperature

• To communicate with satellites

Which type of telescope was invented first?

• Reflecting telescope

• Refracting telescope

• Radio telescope

• X-ray telescope

What is a key feature of refracting telescopes?

• They are the largest telescopes

• They use mirrors

• They use two simple lenses

• They are used for radio waves

What advantage do reflecting telescopes have over refracting telescopes?

• They are smaller

• They use lenses

• They can be made much larger

• They are portable

What is one benefit of using mirrors in reflecting telescopes?

• They are cheaper to produce

• They allow viewing of dimmer objects

• They are easier to clean

• They are lighter
