Stars Module 3 Review

On April 5, 1991, a space telescope was launched aboard the space shuttle Atlantis. This observatory used four primary instruments to locate and observe high-energy radiation in space. Radio waves have the longest wavelengths and lowest energy on the electromagnetic spectrum. The high-energy radiation being observed by the space telescope has the shortest wavelength. What is it called?

• X-rays

• infrared radiation

• gamma rays

• ultraviolet radiation

The diagram below shows the basic structure of the Sun

Material near the core is carried out toward the surface of the Sun and back in by convection currents. What happens to the material as it moves with these currents?

• It becomes hotter as it moves closer to the corona.

• It heats up and becomes part of the Sun's atmosphere.

• It causes the photosphere and surface temperature to become hotter.

• It becomes cooler as it moves through the photosphere toward the surface.

Which of the following is NOT a way the Hubble Space Telescope helps scientists?

• It allows scientists to see deeper into space.

• It lets scientists see space objects in more detail.

• It lets scientists see objects on Earth in more detail.

• It allows scientists to see a greater number of stars.

Based on the picture, which of the following is true about the Sun?

• The Sun is an old-aged star.

• The Sun is an average-sized star.

• The Sun is smaller than most other stars.

• The Sun is younger than most other stars.

Solar prominences are caused by the magnetic fields and electrical currents in the Sun. The diagram below shows a cross-section of the Sun

Which feature in the cross-section of the Sun is the solar prominence?

• W

• X

• Y

• Z

Which of the following best describes the star Arcturus?

• Dimmer than most main sequence stars and has a relatively low temperature.

• Brighter than most main sequence stars but has a relatively low temperature.

• Brighter than most supergiant stars and has a relatively high temperature.

• Dimmer than most supergiant stars but has a relatively high temperature.

Which statement accurately compares a radio wave and an infrared wave?

• A radio wave has a longer wavelength and a lower frequency than an infrared wave.

• A radio wave has a longer wavelength and a higher frequency than an infrared wave.

• A radio wave has a shorter wavelength and a lower frequency than an infrared wave.

• A radio wave has a shorter wavelength and a higher frequency than an infrared wave.

Around 1910, two astronomers named Ejnar Hertzsprung and Henry Norris Russell discovered a relationship that the stars in the main sequence have in common. What is this relationship?

• Stars with greater magnitudes tend to have lower temperatures.

• Stars with greater magnitudes tend to have higher temperatures.

• Stars with greater temperatures tend to have lower magnitudes.

• Stars with greater masses tend to have lower temperatures.

Electromagnetic radiation from space travels in waves, which may be detected by radio telescopes and optical telescopes. How are these telescopes different?

• Both telescopes collect radio waves and visible light, but radio telescopes are much larger.

• The telescopes collect different wavelengths of electromagnetic radiation. Radio telescopes collect radio waves, which are shorter than visible light waves.

• The telescopes collect different wavelengths of electromagnetic radiation. Radio telescopes collect radio waves, which are longer than visible light waves.

• The telescopes differ in the lens size used to collect electromagnetic radiation from space.

Gravity is an important force that affects everything in the solar system, including the sun

In which way is gravity vital to the function of the sun?

• It causes the rotation of the sun, which keeps the sun balanced.

• It allows the radiation of heat from the sun toward all of the planets.

• It causes movement within the convection zone, which produces heat.

• It provides the pressure that causes hydrogen atoms to fuse into helium.
