6.2-6.5 Digital Lesson Flashcards
Solar system that contains one, two, or more then 2 stars
One: single star
Two: binary star system
More then 2: multiple star systems
Since stars are made up of gas they have structure
True
Once nuclear fusion begins, what do stars emit
Visible light and other forms of energy
When stars form during the early part of their life cycle, what is blown away
Dust and clouds
What takes place in the core of a star for most of its life cycle
Fusion
Nuclear fusion
When the atoms come together
Nuclear fission
The separating of atoms
Planetary nebulae
Expanding shells of gasses

False
Black hole
When the core of a supergiant star collapses. Forms a black hole if it had a large mass
Coolest stars
Red dwarfs
Can infrared radiation be seen with the naked eye
No
How can electromagnetic waves be described
Wavelength, frequency, and energy
Energy is the ability to do
Work
A higher frequency means a _________ wavelength. A lower frequency means a __________ wavelength
Shorter;higher
Can EM waves carry light
Yes
Can all EM waves travel at the same speed
Yes
Can wavelength determine the type of radiation for an EM wave
Yes
Is visible light the only type of EM wave that humans can see
Yea
Does earths atmosphere not absorb dangerous gamma waves from space
No
Continuous spectrum
Unbroken band of color that shows that it’s source is emitting light of all visible wavelengths
Emission spectrum
Series of unevenly spaced lines of color and brightness which show that the light source is emoting only certain wavelengths
Absorption spectrum
Continuous spectrum crossed by dark lines
