Exam 1 Flashcards
electromagnetic radiation
the radiant energy released by certain electromagnetic processes (different forms of light and waves)
Who linked electricity with magnetism?
Hans Oersted
James Clerk Maxwell
speculated that electricity and magnetism often work together
Kinds of waves
Radio microwave infrared visible ultraviolet x-ray gamma
what is the only electromagnetic wave that the human eye can see
visible light
formula for light calculations
(c=fλ)
Gauss’ law
relates the distribution of the electric charge throughout the electric field
Gauss’ law of magnetism
there are no monopolies: where there is a south pole there is a north pole
Faraday’s law
says that any change to the magnetic environment can cause voltage to be induced onto a coil
Ampere’s law
describes that the magnetic field created by the electrical current is proportional to the size of the electric current
Solar Flares
occur when magnetic energy builds up in the solar atmosphere and is suddenly released
solar radiation
the energy that radiates from the sun in the form of electromagnetic waves
what kind of barrier does our atmosphere provide
ultraviolet light barrier
what kind of barrier does the magnetosphere provide
magnetic barrier
Example of electrically charged particles are ejected from the sun causing gas atoms in the sky to glow that are attracted to the North Pole
Aurora Borealis
