Using the electromagnetic spectrum, astronomers are able to determine all of the following except-
chemical composition
temperature of the star
organisms present on planets orbiting the star
planets that orbit the star
Which of the following properties can be determined by the colors of spectral lines of stars? (can pick more than one)
distance
luminosity
chemical composition

Quasars are extremely distant celestial bodies. Investigators using a special telescope determined that a certain quasar was emitting waves with a frequency of 1.41×109Hz. An electromagnetic spectrum is shown. The scientists were most likely using a telescope that detects -
microwaves
x-rays
visible light

comet
black hole
asteroid
star
Why does the Earth receive more energy from the sun than it's next closest star, Proxima Centauri?
the sun is larger
the sun is hotter
the sun is closer
the sun is more dense
Why does the sun appear brighter than the supergiant star Betelgeuse?
the sun is a different color
the sun is older
the sun is closer
the sun is made of different elements
Which describes the relationship between the Sun and Milky Way galaxy?
The Sun is a giant-sized star near the center of a disc-shaped galaxy called the Milky Way.
The Sun is a medium-sized star near the center of a disc-shaped galaxy called the Milky Way
The Sun is a medium-sized star near the edge of a disc-shaped galaxy called the Milky Way.

Spectral Class O
Spectral Class B
Spectral Class A
Spectral Class M
Jocelyn Bell Burnell and Antony Hewish discovered a new type of star in 1967. They found an area that was not showing visible light but would emit a radio wave every 1.33 seconds. These stars came to be known as pulsars due to their pulsating radio wave pattern.
The equipment that would have been used would be tuned to which frequency on the electromagnetic spectrum?
2.41 × 1016 Hz
3.72 × 103 Hz
5.34 × 106 Hz
How do radio waves compare to light waves?
Visible light waves have longer wavelengths and more energy than radio waves
Visible light waves have shorter wavelengths and more energy than radio waves.
Visible light waves have longer wavelengths and less energy than radio waves
