How does the tanning equipment work?
A. Tanning equipment basically imitates the sun. The sun emits 3 types of UV rays; namely UVA, UVB and UVC. Of the 3 radiations, UV-C has the shortest wavelength and is also the most harmful radiatio, but it’s absorbed by the ozone layer and pollution. UVB, the middle wavelength, starts the tanning process but overexposure to it can cause sunburn. UVA has the longest wavelength and it completes the tanning process.
