Mirrors were used to extend the pathlength of the optical signal, creating a transmission distance of 35 meters.
The refractive index of water at 20 °C for visible light is 1.33. The refractive index of normal ice is 1.31 (from List of refractive indices). In general, an index of refraction is a complex number with real and imaginary parts, where the latter indicates the strength of absorption loss at a particular wavelength. In the visible part of the electromagnetic spectrum, the imaginary part of the refractive index is very small. However, water and ice absorb in infrared and close the infrared at… WebThe water molecule has three fundamental molecular vibrations. The O-H stretching vibrations give rise to absorption bands with band origins at 3657 cm −1 (ν 1, 2.734 μm) and 3756 cm −1 (ν 3, 2.662 μm) in the gas phase. …
