Thus, we divide the speed of light by that frequency. Using 299,727,738 m/sec (the speed of light at Earth's surface): 299727738 meters/sec divided by 483785116221440 cycles/sec = 6.19547249285e-07 meters. This is equivalent to 6195.4725 ÃngstrÃ¶ms, Ã¥ngstrÃ¶ms which lies in the orange area of the visible light. spectrumo convert the middle audio octave to light (wavelength) we must first raise the note (frequency) forty octaves (frequency times 2, forty times). Example: To convert middle A (440 Hz)to its corresponding wavelength in the visible spectrum.
