Telescopes Flashcard

Front

What is a telescope?

Back

A telescope is an optical instrument that gathers and magnifies light to observe distant objects, such as stars and planets.

What is a spectrometer used for?

Back

A spectrometer is used to analyze the light spectrum from objects, helping to identify their composition.

What is the spectrum?

Back

The spectrum is a range of different colors produced when light is dispersed, often used to identify elements in stars.

Front

What is the unique pattern of black lines in a spectrum called?

Back

The unique pattern of black lines is called a 'fingerprint' and helps identify specific elements.

What is the advantage of using radio telescopes?

Back

Radio telescopes can observe celestial objects regardless of weather conditions, unlike optical telescopes.

Front

What is the Hubble Space Telescope?

Back

The Hubble Space Telescope is a space-based telescope launched in 1990 that has provided significant astronomical data.

Front

What is light refraction?

Back

Light refraction is the bending of light as it passes from one medium to another, which is a principle used in telescopes.

Front

What is the difference between a refracting telescope and a reflecting telescope?

Back

A refracting telescope uses lenses to bend light, while a reflecting telescope uses mirrors to gather and focus light.

Front

What is the role of lenses in a telescope?

Back

Lenses in a telescope focus light to create a magnified image of distant objects.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, and X-rays.
