Each participant was given a small handheld flashlight that emitted a red light with a wavelength of 670 nanometers. They spent three minutes each day looking into the light over a period of two weeks. The lights work on both cones (视锥细胞) and rods (视杆细胞) in the eye. Cones ...
Optical wavelengths can be specified for propagation in vacuum (vacuum wavelength) or in air. These two values are quite similar, since the refractive index of air is only very slightly above 1. For example, a vacuum wavelength of 1000 nm would be 999.7259 nm in standard air; there is a ...
