electromagnetivitiy Flashcards
lowest energy to highest energy of “waves”
-> ie: xrays
7 in total
1) radio
2) microwaves
3) infrared lights
4) visible lights
5) UV lights
6) x-rays
7) gamma rays
which one of these have the longest wave length?
radio waves
which one of these have the shortest wave lengths
gamma waves
whats the connection between wave length and energy?
they are opposites! the more energy produced, the shorter the wave length. (and vise versa)
what is an example of 3 items that use radio waves?
radio
tv
what is an example of 3 items that use microwaves?
microwaves
telecommunications
what is an example of 3 items that use infrared lights?
remote controls
lasers
what is an example of 3 items that use visible lights?
rainbows
concert lights
human vision
what is an example of 3 items that use ultraviolet lights

“black light”
what is an example of 3 items that use x-rays?
medical imaging
cancer treatment
what is an example of 3 items that use gamma rays?

who is thomas young?
a english physicist that showed that light has wave-like frequencies
who is james maxwell?
a man who predicted the connection between electricity and magnetism
electromagnectice waves do not require a medium for transmission and these waves travel at the speed of light
who is heinrich hertz?
discovvered radio waves
who is william konrad roentgen
discovered xrays
