Unit 3 Chapter 5.1 Telescopes pop Quiz

Noah, Abigail, and Charlotte are stargazing. They are using a telescope. What problem does the telescope solve for them?

• It allows them to see things not visible with their eyes alone

• It allows them to see things closer to them

• It allows them to see things in outer space

• It allows them to see things in the dark

Luna, Grace, and Isla are stargazing with a telescope. Why would they want a telescope with high light-gathering power?

• To collect more light than their eyes can and increase the brightness of the stars they are observing

• To collect more light than their eyes can and increase the amount of detail they can see in the stars

• To collect more light than their eyes can and increase the size of the telescope

• To collect more light than their eyes can and increase the resolving power of the telescope

Zoe, Benjamin, and Michael are in a science class learning about telescopes. Their teacher explains that bigger telescopes have more light gathering power. Michael asks, 'Why do bigger telescopes have more light gathering power?'

• Because they have a stronger lens or mirror

• Because they have a better focusing mechanism

• Because they have a bigger detecting area (lens or mirror)

• Because they have a higher magnification power

Mason, Lily, and Luna are on a field trip to an observatory. They see different types of telescopes. Mason is curious to know which type of telescopes use mirrors to gather and focus light?

• Refractors

• Reflectors

• Magnifiers

• Amplifiers

Aria, Mason, and Olivia are on a field trip to an astronomy observatory. They learn that a certain type of telescope is now used almost exclusively by astronomers. Which type of telescope is it?

• Reflectors

• Refractors

• Magnifiers

• Amplifiers

Emma, Liam, and Noah are learning about telescopes in their science class. Their teacher explains that telescopes can be used to observe distant objects. Emma asks, 'How do telescopes make distant objects appear closer?'

• By increasing the size of the object

• By magnifying the light from the object

• By reducing the distance between the object and the observer

• By increasing the brightness of the object

Oliver, Ava, and Isabella are on a field trip to a space observatory. They learn about different types of telescopes. Isabella is curious to know, 'What type of telescope uses lenses to gather and focus light?'

• Reflectors

• Refractors

• Magnifiers

• Amplifiers

Sophia, Mia, and Charlotte are stargazing with a telescope. They wonder why some stars appear brighter than others. What could be the reason?

• The brighter stars are closer to the Earth

• The brighter stars are larger in size

• The brighter stars emit more light

• All of the above

Oliver, Ava, and Isabella are on a field trip to a space observatory. They learn about different types of telescopes. Oliver is curious to know, 'What is the main advantage of reflector telescopes over refractor telescopes?'

• They are cheaper to make

• They do not suffer from chromatic aberration

• They can be made much larger

• All of the above

Emma, Liam, and Noah are learning about telescopes in their science class. Their teacher explains that telescopes can be used to observe distant objects. Liam asks, 'What is the term for the ability of a telescope to distinguish between two close objects?'

• Magnification

• Light-gathering power

• Resolving power

• Focusing power
