Other functions like abs, sin, pow, etc, are provided but they can also all operate on vector quantities, i.e. pow(vec3(1.5, 2.0, 2.5), abs(vec3(0.1, -0.2, 0.3))). GLSL supports function overloading (for both built-in functions and operators, and user-defined functions), so there might be multiple function definitions with the same name, having ...
A much shorter wavelength (~6.7 nm) would be beyond EUV, and is often referred to as BEUV (beyond extreme ultraviolet). [336] With current technology, BEUV wavelengths would have worse shot noise effects without ensuring sufficient dose. [337] (The generally accepted 'border' of UV is 10nm below which the (soft) x-ray region begins.)
The refractive index of water at 20 °C for visible light is 1.33. [1] 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.
An MED is the amount of UV radiation that will produce erythema (redness of the skin) within a few hours of exposure. [26] High-pressure beds use smaller, higher-wattage quartz bulbs and emit a higher percentage of UVA. [27] They may emit 10–15 times more UVA than the midday sun, [20] and have a shorter maximum exposure time (typically 10 ...
