electromagnetic waves

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
