Classification and Properties of Stars
This is the color of the hottest stars.
What is blue?
This is the part of the Sun where nuclear fusion occurs.
What is the Sun's core?
This characteristic of electromagnetic radiation determines visible light's color.
What is the light's wavelength?
These interactions of light allow us to see the world around us.
What are reflection and refraction?
This type of star has cooled and expanded significantly because it is beginning to run out of fuel.
What is a red giant star?
This is another word for absolute magnitude.
What is luminosity?
This is the part of the Sun that you are able to see from Earth during a Solar Eclipse.
What is the Sun's corona?
This type of EM radiation is produced by the Sun and can damage our skin and cause a sunburn.
What is ultraviolet radiation?
This occurs when light travels from one medium into another.
What is refraction?
This piece of technology is used to detect absorption lines, which helps scientists determine a star's composition.
What is a spectroscope?
This is the star classification for our Sun.
What is a Main Sequence Star?
This is the part of the Sun where material that is heated near the core rises, is cooled closer to the surface, and then sinks back down again.
What is the Sun's convection zone?
This type of EM radiation can be used in the medical field to treat cancer patients.
What is gamma radiation?
This type of medium does not allow mechanical waves, such as sound waves, to pass through.
What is a vaccuum?
This feature of the Sun is a large bright stream of solar particles that arches from one sunspot to another and can extend out into the Sun's corona.
What is a solar prominence?
This feature of a star is indicated by the star's color.
What is the star's temperature?
This is the part of the Sun that has sun spots that can be seen from Earth.
What is the Sun's photosphere?
We can detect this type of EM radiation as heat using special devices.
This quality of a medium determines the speed at which mechanical waves, such as sound waves, can travel.
This type of star is what is left of dying star if it is massive enough to create a supernova, but NOT massive enough for the core to collapse into a black hole.
What is a neutron star?
This feature of a star is determined by the star's absolute magnitude, size, and distance from Earth.
This type of heat transfer occurs when the Sun's light and heat travels through empty space and arrives at Earth.
What is radiation?
This side of the EM spectrum has the most energetic types of EM radiation that can be harmful to people.
What is the right side of the EM spectrum (or the shorter wavelength side)?
This characteristic of sound is directly proportional to the sound wave's wavelength.
What is the sound's pitch?
This phenomenon creates a rainbow.
What is the refraction of the different wavelengths of visible light at different speeds through a prism?
