Domestic microwave ovens use microwaves that have a wavelength of 122 mm.
WebThe terms “light” and “visible radiation” (VIS) refer to the wavelength range between 360 nm and 830 nm, which can be perceived by the human eye. Optical radiation with wavelengths shorter than 400 nm is called ultraviolet (UV) radiation and is further subdivided in UV-A, UV-B and UV-C ranges. Optical radiation with wavelengths longer ... WebFeb 12, 2024 · Depending on the range of wavelength of light source, it can be classified into two different types: UV-visible spectrophotometer: uses light over the ultraviolet range (185 - 400 nm) and visible range (400 - 700 nm) of electromagnetic radiation spectrum.
WebApr 24, 2024 · Ultraviolet (UV) radiation covers the wavelength range of 100–400 nm, which is a higher frequency and lower wavelength than visible light. UV radiation comes naturally from the sun, but it can also be created by artificial sources used in industry, commerce and recreation.
