264 nm.
Infrared has a smaller wavelength than microwaves.
To determine UV-absorption you need to use UV-light. And there's a defined wavelength for UV-light.
UV light has a shorter wavelength than infrared.
No, ultraviolet radiation has shorter wavelengths than violet light. Violet light is at the end of the visible light spectrum with longer wavelengths compared to ultraviolet radiation, which falls just beyond the violet end of the spectrum.
Yes, a "black light" is an ultraviolet light with wavelength of about 395-410 nm.
The shortest wavelengths have the most energy because it has the highest frequency. A high energy light will have a shorter wavelength than a low energy light. If the wavelength goes down, then the frequency goes up. When calculating energy in the equation, E=hv, frequency (v) is the variable, not the wavelength. So in the equation, if you wanted a more energy (E), you would have the frequency be large. For the frequency to be big, then the wavelength has to be low. So no UV light doesn't have the most energy Gamma rays do though.
UV light appears purple because it has a shorter wavelength than visible light, causing it to be perceived as a different color by our eyes.
According to <http:/www.heraeus-noblelight.com/en/uv-disinfection-oxidation/information-for-disinfection-and-oxidation/services-and-events/emission-spectra-of-germicidal-lamps.html> 254nm appears to be the most common. Shorter wavelengths appear to create ozone
The wavelength for ultraviolet (UV) light ranges from 10 to 400 nanometers (nm). UV light is invisible to the human eye but is commonly found in sunlight and can have harmful effects on the skin with overexposure.
UV light iddivided in to three. UV-C wave length from 100nm to 280nm. UV-B 280nm to 315nm and UV-A 315nm to 400nm. The wave length of 254nm (UV-C) is giving maximum germicidal activity and it is not too irritating.
UV light has higher frequency, so it has more energy than red light has
