with EMR

A Day in the Life of a Spy with EMR

Radio waves are among the longest in the electromagnetic spectrum while X-Rays and radioactive waves are among the shortest. As the wavelength decreases the

strength of the wave increases.

To: 007

Mission is a go.

From: HQ (MI6)

Radio waves provide me with my next mission.

The waves sent from one end of the radio are tuned to a specific frequency or wavelength. At the other end the electromagnetic waves are

received and converted into mechanical vibrations which can be heard. These waves are the longest of the spectrum but have the lowest frequency.

Radio waves are used in many sources such as AM radios, FM radios, cell phones, televisions, etc.

Objects in space such as other planets and galaxies emit light in extremely long wavelengths

which are classified as radio waves in the spectrum.

Microwaves and radar help me locate the enemy island hideout.

Microwaves are significantly shorter than radio waves. They are used commonly to transmit information from one source to

another because the wave energy can penetrate through clouds, smoke rain and

snow. They are also beneficial because they are focused into narrow beams for

direct transmissions of high levels of data.

Microwaves are used in many things such as radar, microwave ovens, communication

transmissions, GPS, etc.

Refraction of myself from water to the air caused an illusion and helped me to pass by the enemy guards.

Refraction is the deflection or bending of electromagnetic waves when they pass through one medium to another. Materials with

differing indexes of refraction will cause the waves to bend towards perpendicular of the other material until the wave has

passed through then away from perpendicular again.

Refraction is used in objects such as telescopes and glasses bending light in determined ways.

Infrared waves and night-vision help me stalk my enemy in the

dark of the night.

Infrared waves have a slightly longer wavelength than visible

light. Infrared energy is sensed as heat slightly cooler than visible

heat. Because of this we use night-vision or infrared cameras to see

the infrared waves our eyes cannot pick up.

Such things as humans and animals create infrared heat as well as the universe and the dust between stars.

X-Rays show my injuries after fierce physical hand-to-hand

battles subduing violent criminals.

X-Rays are among some of the most energetic and smallest waves in the spectrum only behind

Gamma rays. X-ray waves come from objects that are extremely hot such as the

sun.X-rays are also commonly use in medicine to take pictures of bones under the skin by

firing streams of x-rays through your body.

• Electromagnetic radiation waves (EMR) are an important part of society throughout

the entire world and the universe, for we interact with them every moment of

everyday. Whether we are communicating or surviving on earth these waves are

constantly surrounding us and filling the space between the planets around ours.

• Similar to Electromagnetic radiation and secret spies, just because you don’t see

them doesn’t mean they’re not there.
