    Hi,

    If I have a transmitter that can transmit frequencies ranging from 400 to 789 Terahertz and I transmit a frequency of 400 Terahertz.
    Would I see the color Red in the Visible Spectrum on air?

    That would be terrible! It will fill a particular area color Red.

    Thanks!

    Lightfire, I have posted a photo of a transmitter like the one you speak of. They exist, and they have existed since the mid-1920s. There are different transmitters to produce different colors, and they are very common today. Here's a picture: High Frequency Transmitter

    DerStrom8, but I want a transmitter like a dish transmitter. I'm just wondering if it has 100 kilowatts power, would that fill a very big place with red color?

    pls. help.

    Yes but no. There are no dish transmitters that can transmit at that frequency, and they are not designed to. They are made to transmit much lower frequencies. You'd be better off getting a huge red light bulb, as mentioned before.
