UVC radiation may be produced by which process?

Explanation:
UVC radiation comes from very energetic photon emission produced by extremely hot sources. The electric arc in arc welding creates a plasma at thousands of degrees, emitting a broad spectrum that includes ultraviolet light, reaching into the UVC range. That intense UV output is why welders wear protective eyewear and clothing to guard against skin and eye damage. Infrared drying emits primarily infrared radiation as heat, not UV. Microwave heating excites molecules with microwaves rather than producing UV photons. Visible light bulbs mainly emit visible light; they’re not a significant source of UVC. So arc welding is the process that can produce UVC radiation.
