Hello all,
We know that visible light approximate frequency range is 400-700 Tera Hertz (THz). Human eye can see this spectrum of electromagnetic wave. AC power electricity have frequency of 50-60 Hz. therefore electric lamp light and the light that reflect from objects have 50-60 Hz frequency. thus why we can see such wave with low frequency???
Thanks in advance...
