Although there are many scales of light rays, we hear UV rays most often because of their many uses. Notable among them are-
350-370 nanometers: Used to attract flies or insects.
300-320 nanometers: Used in light therapy.
300-365 nanometers: Used in printing ink or polymer versions.
250-300 nanometers: Used in forensic analysis or drug detection.
270-300 nanometers: Used in protein analysis, DNA synthesis, or drug preparation.
230-365 nanometers: Used for identification of national identity cards, barcodes, or labels.
230-400 nanometers: Used to make light sensors in electronics.
Although it has many beneficial uses, it is also directly harmful to us. When ultraviolet rays fall on the skin, some of the cells inside our skin are broken or destroyed. As a result, the tension of the skin is gradually lost. That’s why those who work more in the sunlight, their skin shrinks quickly, wrinkles fall, and the skin shows signs of aging quickly. Loss of skin moisture, dullness, dark spots, etc. can be caused by the effect of ultraviolet rays.
However, several layers of the atmosphere are protected from the ultraviolet rays of our sun.
