Fun Fact 2: What are electromagnetic waves used for? Microwaves, X-rays
and light are some good examples of the way we use electromagnet waves.
Fun Fact 3: Radiant energy is produced naturally. It can be visible or
invisible to the human eye.
Fun Fact 4: Who discovered radiant energy? Radiant energy was discovered
in the late 1800s by a British chemist and physicist known as Sir
Fun Fact 5: The unit of measurement used for measuring radiant energy is
Fun Fact 6: What can produce radiant energies? Anything which has a
temperature can produces radiant energies, providing its temperature is
different to the absolute zero.
Fun Fact 7: Sunlight produces radiant energy. The speed of light is
quicker than any other speed including sound.
Fun Fact 8: Radiant Energies travel only in a direct line.
Fun Fact 9: Radiant Energy can pass through many types of matter
including gaseous, liquid and solids.
Fun Fact 10: Radiant Energy can be absorbed, transmitted or reflected.
It will be reflected when an object is unable to absorb the radiant
Fun Fact 11: Radiant Energy does not require matter in order to be
transmitted. It can even travel in a vacuum environment.
Fun Fact 12: Radiant Energy is a form of kinetic energy. The definition
of kinetic is the energy produced when an object is in motion. This is a
moving energy type, it is not still.
Fun Fact 13: Life on earth would no longer exist without radiant energy.
It is an absolute requirement for the survival of living things.
Fun Fact 14: Radiant Energy can be used in telecommunications, heating,
lighting and many other important processes.
Fun Fact 15: Examples of radiant energy; some good examples of radiant
energy production include the heat produced from a campfire, the
conversion of solar energy to heat, microwaves, X-rays and mobiles
