Trenton swallow Flashcards
solar nebula
solar nebula is a cloud of dust and gas
gravity
gravity is a force the pull material down to earth
fusion
fusion is when you connect two or more things together and make a strong connection
star
star is a fixed light during the night that is like the sun
infrared light
infrared light is a light that is a light that we can not see
visible light
visible light is a thing of electromagnet radiation
ultraviolet light
ultraviolet light is a thing of radiation that human can not see
matter
matter is a substance as distinct mind and spirit
planetary
planetary is related or is owned by a planet or planets
nebula
nebula is a cloud of dust and gas in outer space
white dwarf
white dwarf is a small but thick star that is often the size of a planet
red giant
red giant is a huge star that has a large amount of luminosity and has a low surface temp
main sequence star
main sequence star is a continuous belt of stars that are made up of many colors
electromagnetic
electromagnetic is similar to electric currents and magnetic fields
spectrum
spectrum is a belt of many colors kinda like a rainbow
element
element is something that is uneven so abstract
hydrogen
hydrogen is a gas that has no color and no smell
helium
helium is the lightest gas ever
proton
proton is a stable subatomic partical
neutron
neutron is a subatomic particle similar to proton
nucleus
nucleus is the most important part of a material
photon
photon is a particle representing a amount of light or electromagnetic radiations
cosmology
the branch of astronomy that deals with the general structure and evolution of the universe.
universe
the totality of known or supposed objects and phenomena throughout space
big bang theory
a theory that deduces a cataclysmic birth of the universe big bang from the observed expansion of the universe, cosmic background radiation abundance of the elements, and the laws of physics.
emission spectrom
the spectrum formed by electromagnetic radiations emitted by a given source characteristic of the source and the type of excitation inducing the radiations.
spectrometer
an optical device for measuring wavelengths deviation of refracted rays and angles between faces of a prism
wave length
the distance, measured in the direction of propagation of a wave between two successive points in the wave that are characterized by the same phase of oscillation.
Frequency
the state or fact of being frequent so a frequent occurrence
exspansion
the act or process of expanding– getting larger
contraction
an act or instance of contracting.
galaxy
a large system of stars held together by mutual gravitation and isolated from similar systems by vast regions of space.
redshift
a shift toward longer wavelengths of the spectral lines emitted by a celestial object that is caused by the object moving away from the earth.
blue shift
a shift toward shorter wavelengths of the spectral lines of a celestial object caused by the motion of the object toward the observer.
doppler affect
the shift in frequency of acoustic or electromagnetic radiation emitted by a source moving relative to an observer as perceived by the observer: the shift is to higher frequencies when the source approaches and to lower frequencies when it recedes.
Gravitation
the force of attraction between any two masses.
Plasma
Anatomy Physiology the liquid part of blood or lymph as distinguished from the suspended elements.
Solar System
the sun together with all the planets and other bodies that revolve around it.
Absorption Spectrum
the spectrum formed by electromagnetic radiation that has passed through a medium in which radiation of certain frequencies is absorbed.
