Electromagnetic Spectrum kaitlyn ferguson

The longer the wave length, the lower the frequency. the shorter the wave length, the higher the frequency.

Each wave on the spectrum has its own specific wavelength and frequency. Radio waves have the longest wavelength and the lowest frequency. As you go further down the spectrum the wavelengths get shorter and the frequencies get higher. Gamma rays have the shortest wavelengths and the highest frequency.

Radio Waves

radio waves are the waves with the longest wavelength and the lowest frequency. They include microwaves and broadcast waves. THEY'RE used for radio and T.V.

Micro Waves

Radio waves with the shortest wavelengths and the highest frequencies are Microwaves. Microwaves are used for cell phones, Radar, and microwaves.

Infrared Waves

Infrared waves have a shorter wavelength and a higher frequency than radio and microwaves. THEY are used for HEAT LAMPS, electric stoves,and infrared camera.

Visible Light

These are waves you can see. The visible light waves with the longest wavelengths are red and the ones with the shortest appear to be violet.

Ultraviolet Rays

Ultraviolet rays have a slightly shorter WAVELENGTHs than visible light. The ENERGY of ultraviolet rays is so high so THEY'RE used to kill bacteria or kill diseases. Ultraviolet waves can also damage your skin in eyes. Applying sunblock and wearing sunglasses with prevent this.


X-rays have slightly shorter wavelengths than ultraviolet waves. Because they have a high frequency, they have a lot of energy. Therefore, they can grow through most matter, except for dense materials like lead or bone. So doctors use x-rays to create images of peoples bones.

Gamma Rays

Gamma rays have the shortest wavelengths and the highest frequencies. They are the most penetrating due to their high energy. They are used for medical purposes, such as killing cancer cells. Gamma rays can be produced by objects in space or nuclear reactions.

Radio Waves

SOCIETY uses Radio waves to carry information, which we can use for radio and television


Society uses microwaves to transmit cell phone messages and to cook food

Infrared Rays

Infrared rays are used to cook food like toast

Visible Light

visible light allows us to see color

Ultraviolet Rays

Ultraviolet rays provide us with vitamin d


Society uses x-rays to view the inside of peoples bodies in order to treat medical problems

Gamma Rays

Doctors use gamma rays to treat cancer by killing tumors without destroying other areas of the body
