Earth Science Chapter 24 Test

Front

What is light-gathering power in telescopes?

Back

Light-gathering power refers to a telescope's ability to intercept more light from distant objects, producing brighter images.

Front

From where do we obtain the majority of our information about the universe?

Back

The vast majority of our information about the universe is obtained from the study of the light emitted from stars and other bodies in space.

Front

How does a refracting telescope produce an image?

Back

A refracting telescope produces an image by using a convex lens to bend and focus light.

Front

How can astronomers determine if a star is moving toward or away from Earth?

Back

Astronomers can determine whether a star is moving toward or away from Earth by analyzing the star's spectrum for Doppler shifts.

Front

When was the Hubble Space Telescope launched into orbit?

Back

The Hubble Space Telescope was put into orbit around Earth in 1990.

Front

What is the function of a convex lens in a refracting telescope?

Back

The convex lens in a refracting telescope bends and focuses light to form an image.

Front

What is the significance of Doppler shifts in astronomy?

Back

Doppler shifts are significant in astronomy as they help determine the motion of stars and galaxies relative to Earth.

Front

What type of light do astronomers study to learn about distant celestial objects?

Back

Astronomers study visible light, as well as other wavelengths such as infrared and ultraviolet, emitted from celestial objects.

Front

What is the primary advantage of using space telescopes like Hubble?

Back

The primary advantage of using space telescopes is that they can observe celestial objects without the interference of Earth's atmosphere.

Front

What is the role of mirrors in reflecting telescopes?

Back

Mirrors in reflecting telescopes gather and focus light to form images, allowing for larger apertures and clearer views.
