Electromamgnetic Radiation Part 1

What is electromagnetic radiation? 

Electromagnetic radiation is a group of different kinds of electromagnetic energy. It can be emitted from different sources. The higher the frequency, it goes to a different form of radiation with more energy.  

How can it be used? 

Forms of electromagnetic radiation can still have their own frequencies. For example, radio wave 1, has a different frequency from radio wave 2. That's how information is transported through radio. The radio converts the frequency and amplitude of the sound into radio waves, which are converted and transmitted to another radio. That other radio will then convert the radio waves into sound. 

What are radio waves? 

Radio waves are the weakest form of electromagnetic radiation, meaning it is the form with the lowest frequency. Due to there being a wide range of different frequencies for radio waves, it is normally used for communication; people use it for radios because there are lots of different. 

What are microwaves? 

Microwaves are another form of electromagnetic radiation. They have a lower frequency than infrared light but have a higher frequency than radio waves. They are normally used to increase the speed of H2O molecules in substances to make it eligible for consumption; heat up the water in food to cook it.
