ELECTROMAGNETIC ENERGY
BY: Alora.M
HOW DOES IT WORK?
Electro magnetic energy is when you transmit
one energy source to another by using waves.
This can be in light, heat or any other form. You
do this by using two magnets that are used to
spin a wire.
 Electromagnetic energy is the energy that comes
from electromagnetic radiation. This radiation is
composed of waves, such as radio waves and
visible light, that move at the speed of light in a
way that is suggestive of both waves and
particles.

COMMON USES
Radio waves
 TV waves
 Microwave ovens
 Light
 Heat
 Ultraviolet Light
 X-rays
 Radar waves
 Computers
 Refrigerators

PRO’S AND CON’S
Pro’s
Easy to generate
 Green and not as
polluting as oil and
fossil fuels

Con’s
Not as efficient as
hydrocarbon energy
sources
 Can get incredibly
hot due to electrical
resistance
 Not Easy to achieve
 Some scientist’s
believe is not safe

FUN FACTS!
•The different types of electromagnetic waves
are light, microwaves, x-rays, and TV and radio
transmissions.
 •The higher the energy of the particles of
electromagnetic wave, the shorter the
wavelength.
 When electromagnetic waves enter matter, they
slow down i.e. their energy decreases, hence
wavelength increases.
 •When any object is heated, its particles are
accelerated that causes change in their electric
and magnetic fields, thus forming an
electromagnetic wave.
