what are electromagnetic waves
these are traverse waves Their vibrations or oscillations are changes in electrical and magnetic fields perpendicular to wave travel
what can all electromagnetic waves do?
transfer energy as radiation from source of waves to an absorbed
can travel through a vacuum such as space
travel at same speed through a vacuum through the air
In order name the 7 distinct group electromagnetic waves can be categorised in (low to high)
radio waves
microwaves
infrared radiation
visible light
ultraviolet
x-rays
gamma rays
what are the factors of waves in the lower electro magnetic spectrum as well as those in the upper
lower = long wavelength, low frequency, low energy
upper = very short wavelength, high frequency, high energy
