Please log in for more thread options If light is part of the same spectrum and waveform as radio waves and radio waves can be transmitted through an antena then couldn't visible light? If a sine wave driver was adjusted to run in the visible spectrum and then connected to an earth ground and needle point antena, could visible light be seen coming of off the needle point? | |||||||||||||||||||||||||||||||||||||||||||||||||||||||

--- Yes. --- By the way, has this ever been tried before? --- Considering just the antenna, calculate the length of a 1/4 wave whip at far infrared. -- John Fields Professional Circuit Designer | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
