100
How bright a star looks from Earth.
What is apparent magnitude?
100
The highest point of a wave.
What is the crest?
100
The wave with the shortest wavelength.
What are gamma rays?
100
The area where nuclear fusion takes place.
What is the core?
200
The process that converts hydrogen to helium.
What is nuclear fusion?
200
Why massive stars spend less time in the main sequence than smaller stars.
What is because they use fuel faster than smaller stars?
200
The lowest part of a wave.
What is the trough?
200
Microwaves, radar, and MRI are these kind of waves.
What are radiowaves?
200
Cooler areas on the Sun's surface associated with strong, local magnetic activity.
What are sunspots?
300
The stage the occurs when a star's hydrogen supply has been exhausted.
What is a red giant?
300
The stage when a star has cooled completely and does not glow.
What is a black dwarf?
300
The height of a wave from its resting position.
What is amplitude?
300
You can feel warmth from these waves.
What are infrared rays?
300
A zone where hot blobs of plasma rise, release energy, cool, then drop down to heat again.
What is the convection zone?
400
What is left when a red giant loses its outer layers.
What is a white dwarf?
400
What is left after supernova if a star is less than 9 times larger than the Sun.
What is a neutron star?
400
The number of crests that pass through a point in one second.
What is frequency?
400
The kind of waves with the second highest frequency.
What are x-rays?
400
The upper layer of the Sun's atmosphere.
What is the corona?
500
What is left after supernova if a star is more than 9 times larger than the Sun.
What is a black hole?
500
What forms from the outer layers thrown off of a red giant.
What is planetary nebula?
500
The amount of energy a wave has if it has a high amplitude and short wavelength.
What is a high amount of energy?
500
The electromagnetic waves that you can see.
What is visible light?
500
A release of gas, electrons, visible light, ultraviolet light, and x-rays, caused by sudden magnetic field changes.
What is a solar flare?
