Spongebob's Electromagnetic Spectrum Adventure

Cody J.

Spongebob notices Pats new radio and Sponge is really smart about Science. So he asks Pat if he knows anything about radio waves. Patrick says "UUUUUUhhhhhhhh... whats a radio?" "Well Ill tell ya Pat. Here are just some important things to know about a Radio Wave. The wavelength of a radio wave is 1 millimeter to 100 kilometers. (Patrick is confused) Another thing I'd like to ad Pat is the frequency 100 GHz to as low as 3 kHz. Some other time we could go into what the labels mean. Uses would be transmit TV and radio programmes.

You see Pat you have all kind of waves around you, like your sand microwave. The wavelength ranging from one meter to one milimeter. With frequencys between 300 MHz and 300 GHz. Uses could be to thaw, cook, or heat food.

Another one to add you don't see very much but its our there. Is the infrared wave. The infrared wavelength is 700nm to 1mm. The frequency is 430 THz down to 300 GHz. The infrared wave is used to see living things body temp in color.

Visible light or the part of a wave we can see. "What?" says Pat. This is anoth wave that I was talking about. The wavelength is 400-700nm and the frequency would 430-770THz. The uses are... well it's so we can see.

An ultra violet wave is a wave that makes black-light posters glow and is the reason why we're tan or burnt in the summer. The wavelength is 10nm to 400nm. The frequency is 30PHz to 750THz.

x-rays, you know to look inside a human. Those are also waves. .01nm to 10nm is the wavelength. The frequency ranges from 30petahertz to 30exahertz.

The last one I'd like to explain is gamma rays. 100keV is around the frequency. And 10picometers is around the wavelength. Uses are like for example to see internal organs.
