Physic Assignment Wave uses and effects.

2Mubareks Physics Assignment

Electromagnetic Spectrum is : the range of wavelengths or frequencies over which electromagnetic radiation extends.

What is Electromagnetic Spectrum ?

3Mubareks Physics Assignment

Radio Wave is used for television signals. (Used for communications.

Radio waves have lowest frequency and longest waves.

What are the uses of Radio Waves ?

4Mubareks Physics Assignment

Some claims suggest cell phone RFs may instigate brain tumors and even cancer.

To much Radio waves may cause Cancer .

What are the affects of Radio Waves ?

5Mubareks Physics Assignment

The most common use of infra-red waves is in remote controls for electronic devices and also to send data between such devices. Infra-red, or IR, is also used in thermal imaging, heating, night vision, missile tracking and weather forecasting.

What are the uses of infrared ?

6Mubareks Physics Assignment

Infrared radiation (IR) is electromagnetic radiation with a wavelength between 0.7 and 300 micrometers, which equates to a frequency range between approximately 1 and 430 THz. The main danger of too much infrared to human beings is overheating. The radiations also cause dehydration, a depletion of electrolytes, mobilizing toxins around the body and complicating pre-existing illnesses.

What are the Affect of infrared waves?

Visible light is used during the study of the Earth and the Universe through the use of different instruments that detect different wavelengths. These light wavelengths are normally not visible to the naked eye.

What are the uses of Visible-light ?

8Mubareks Physics Assignment

Laser safety is safe design, use and implementation of lasers to minimize the risk of laseraccidents, especially those involving eye injuries. Since even relatively small amounts of laser lightcan lead to permanent eye injuries

What are the affects of Visible light ?

9Mubareks Physics Assignment

One of the uses : detecting forged bank notes by fluorescence.

And it is used to protect eyes and skin ! .

What are the uses of Ultraviolet?

10Mubareks Physics Assignment

 ultraviolet radiation can cause normal cells to become cancerous.

What are the affect of Ultraviolet?

11Mubareks Physics Assignment

An X-ray is a common imaging test that has been used for decades to help doctors view the inside of the body without having to make an incision.

What are the uses of X-Rays ?

12Mubareks Physics Assignment

There are some harmful effects of an X ray. If a woman is pregnant and has an x ray it can cause tumors to the unborn child. Also, it increases the risk of cancer by 40 percent.

What are the affects of X-Rays ?

13Mubareks Physics Assignment

Gamma rays can provide benefits. Gamma rays are electromagnetic radiation. Gamma rays have short wave lengths and high frequency. We use gamma rays in x-rays, radio waves, and light. Gamma rays can be an effective cancer fighting tool. Doctors treat tumors with gamma rays which essentially kills the cell. Scientist use gamma ray telescopes to explore the galaxy. Being able to research outer space through the use of gamma ray satellites helps us to better understand the world we live in.

The Uses of Gamma Rays?

14Mubareks Physics Assignment

Gamma rays cause cell damage and can cause a variety of cancers.

They cause mutations in growing tissues, so unborn babies are especially vulnerable.
