The Em spectrum
By: Christopher Brock
It has the lowest energy. it has the longest wavelength.
It helps us listen to the radio in the car and lets us use radar
It effects our heath over time if you have it above your house
It can effect our life by if we get to much exposure it can give us luekiema Heinrich hertz
Heinrich hertz discovered radio waves
It has the second lowest frequency , and has the second longest wavelength.
We use it to heat up food in our microwave, And lets us turn on a TV
A danger is it can cloud your eye liens
It effects our life by it we did not have micro waves than we could not warm up food,
James Clark Maxwell discovered micro waves.
It has the third longest wavelength. and the third lowest energy.
When fast food places put your food under the lights it heats up that food that is under it. It can keep a animal warm when it is under a lamp.
It can damage your retina.
it allows us to turn us to turn TV's on at short distances
Frederick William Herschel discovered the infrared
it has a the fourth lowest energy out of the seven. It has the fourth longest wavelength out of the seven.
The lasers in DVD players use it. It helps us see color. Printers use a laser to print things
to much exposure to light can damage you retina
It helps us see color.
It has the fifth highest energy out of the seven. It has the third highest wavelength
It can help us tan. It can help us see stuff that you normally cant see
It can cause skin cancer
It effects our life because if we did not have ultra violet waves then we would have no sun light
Johann Ritter discovered ultra violet.
It has the second highest wavelength and the second highest energy out of the seven
It helps us see if we have a broken bone some were. At the air port they see in your bag
It can cause cancer
it help me see if I have a broken bone
Wilhelm Roentgen discovered xrays.
it has the highest energy in the em spectrum. It has the shortest wavelength in the spectrum.
some uses are it sterilizes medical equipment. it is used in the medial field.
It can kill you is exposed to enough of it.
it effects my life by making me sick if i exposed to it.
Paul Villard discovered gamma rays
