SUMMARY
Using visible light for radio transmission is not feasible due to its short wavelength, which limits diffraction and obstructs communication between devices. While practical applications exist, such as TV remote controls and infrared communication ports, these rely on line-of-sight transmission. Long-distance detection of AM visible light signals from pulsars demonstrates the potential for visibility, but practical communication requires unobstructed paths between devices.
