HS, Physics Std 32: Describe how different components of the of the electromagnetic spectrum are used for communication purposes. Examples: laser radiation, microwave radiation, radio waves

Lesson Plans: Introduction to Satellite Oceanography - The satellite images shown here are of sea surface temperature. The data used to construct these images were obtained with an AVHRR sensor (Advanced Very High Resolution Radiometer) carried on a NOAA satellite (Nation Oceanic and Atmospheric Administration). This sensor measures the amount of thermal infrared radiation given off by the surface of the ocean. It is called 'thermal' radiation because radiation of this frequency warms our skin. A fire feels warm because it gives off lots of radiation at this frequency. The amount of thermal infrared radiation given off by an object is related to its temperature (dying embers give off less radiation than a hot fire and a person gives off even less). Thus by measuring the amount of radiation given off by the ocean we can calculate its temperature.

Another CD Spectroscope A simple laser communicator How would you like to talk over a laser beam? In about 15 minutes you can set up your own laser communication system, using cheap laser pen pointers and a few parts from Radio Shack. Build a simple radio A Groovy CD Experiment Uses lasers and a CD.
