Answer:
100nm-280nm
Explanation:
Ultraviolet rays (UV) are part of the electromagnetic spectrum. It goes from 10nm to 400nm wavelengths, they are shorter than visible light, thus it's impossible to see by a human eye, and larger than X-rays (used in many medical applications and harmful when long-exposed).
According to its wavelengths, UV can be divided in different types:
UVA: long wave UV (315nm-400nm)
UVB: medium-wave UV (280nm-315nm)
UVC: short wave UV (100nm-280nm)
Therefore, UVC comprises wavelengths between 10nm and 280nm.
The minimum and maximum values of wavelength in the UVC region are 100-279 nm.
We know that the Ultraviolet rays, therefore, UV rays are divided into three categories, these categories are UVA, UVB, and UVC.
UVA- The UVA are the rays that are not absorbed by the ozone layer.
UVB- UVB is partially absorbed by the ozone layer
UVC- UVC is completely absorbed by the ozone layer.
The minimum and maximum values of wavelength in the UV region are:
UVA: 315-399 nm
UVB: 280-314 nm
UVC: 100-279 nm
The minimum and maximum values of wavelength in the UVC region are 100-279 nm.
