What is a Radio Wave?

Radio waves have the longest wavelengths out of all of the other waves. They carry signals for your television, cars, and cell phones. Radio Waves can sometimes travel as long as a mile.

Everyday Examples

Televisions and radios and sometimes cell phones, have an antennae on them receive signals in a form of electromagnetic waves, that are broadcasted as music or pictures on your television screen

Microwaves

By Samantha Singer & Rachel Wilson

What Are Microwaves?

• Microwaves are: the radio wave with the smallest wavelength and the highest frequency.

• An every day example of microwaves are: the microwave oven, which is most commonly used.

What Else Do I Need To Know?

• Longer microwaves are used for cooking (microwave oven), and shorter ones can be used for radar (such as weather forecasts).

• Microwave energy can be good for sending information, because the energy can break through haze, snow, smoke, light rain and clouds.

This is the Electromagnetic

Spectrum, in which

Microwaves are part of.

Infrared Light

Infrared

• Light lies between the visible and microwave portions of the electromagnetic spectrum.

• Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light violet.

• “near infrared” light is closest in wavelength to visible light. “far infrared” light is closer to the microwave section of the EM spectrum.

• The longer wavelengths are about the size of a pin head and the smaller ones are the size of cells.

• The temperatures are sensitive nerve endings in our skin can detect the differences between inside body temperature and outside body temperatures.

How we can see using infrared light

• Primary sources infrared radiation is heat or thermal radiation, any object that has temperature radiates in infrared even ice cold objects make infrared, when an object isnt hot enough to radiate visble light it will give most of its energy off in infrared.

• Although humans may not be able to see infrared light rattle snakes have sintered Pitts which allows the snake to detect warm blooded animals. Snakes with 2 sintered Pitts are even thought to have some depth in the infrared.

Ultraviolet Waves

Near Ultraviolet

Near ultraviolet light is the closest out of all three of the types, to visible light. The abbreviation for near ultraviolet light is NUV.

Far Ultraviolet

Far ultraviolet light is lies between the near and extreme ultraviolet regions. Far ultraviolet light is the least explored of the three region. The abbreviation for far ultraviolet light is FUV

Extreme Ultraviolet

Extreme ultraviolet light is the closest out of the three types to X-rays. It is also the most “energetic” of the three. The abbreviation for the extreme ultraviolet light is EUV.

The Sun

The Sun gives of every kind of light. One of those lights is ultraviolet light. Ultraviolet lights are the waves responsible for giving us sunburns. The gases in the atmosphere of the Earth block most of the ultraviolet light but some always gets through. Scientists have developed special telescopes that can see the sun’s ultraviolet light. This diagram shows the ultraviolet

rays from the Sun to Earth. It gets blocked in many places like the stratosphere, and troposphere.

Things That see ultraviolet

While humans cannot see ultraviolet rays other things can, living and nonliving. Some of those things include Bees and certain kinds of telescopes.

X-Rays

By: Alexis Bearss and Tyler Castro

what are X-rays?

• X- rays are electromagnetic hwaves hwith very short hwavelengths. You can not feel X-rays. They have smaller hwavelengths. Therefore they have higher energy than ultraviolet rays.

Ex) going to the dentist. They place a film into your mouth. And the X-rays are shot through the cheekyleeky, capturing your teeth X-ray.

This diagram shows gamma rays moving through a number of dense materials, while other waves and rays

can’t.

GAMMA RAYS

• Gamma rays have the smallest wavelengths and the highest

frequency out of everything else in the electromagnetic spectrum.

• They have the most energy and are also the most penetrating

EXAMPLE

• Gamma Rays are used to kill cancer cells when patients are in radiation

therapy.
