Visible Light

Visible Light

Human only perceives 0.0035% of the electromagnetic spectrum with our eyes. This 0.0035% is known as visible light and comprises everything the human eye alone can detect in the universe. The range of visible light on the electromagnetic spectrum is so small that if you were to lay out the practical electromagnetic spectrum from Los Angeles to New York, the visible wavelengths would be nanometres across, small enough to pass through a surgical mask.
