Pros and Cons of Radio waves

Radio waves  PROS and Cons

Radio waves are used every day in our lives, as they are used to broadcast everything that you hear on the radio and see on your television. They have the lowest frequency and the highest wavelength of the electromagnetic spectrum, and are the least potentially dangerous. There are no real health problems directly associated with radio waves. (Unless you blow your car up with the volume of your radio, but that has to do with sound waves and amplitude, and we don't have any control over what you set that to.) They are the lowest on the electromagnetic spectrum, and are just below microwaves. With these waves, it is possible to communicate with people around the world, and even to other planets in space! One day, some radio signals that we have sent off into space may yet reach another planet with life. Here are some pros and cons of using radio waves.

PROS

    They can be used for communication (This one's for you, phone companies.)
    They do not harm living organisms at all.
    They are available in a wide range of frequencies.
    They can be used to save lives. (For example, radioing someone if you are stuck at sea and need to be rescued.)
    Sometimes used for radar.

cons

    Interference from other radio waves can be a problem.
    Range can also be a problem. (Higher Frequencies = More Range)
