 09:06 30/10/2022

UV là từ viết tắt của Ultraviolet hay còn gọi là tia tử ngoại, tia cực tím là sóng điện từ có bước sóng ngắn hơn bước sóng của ánh sáng nhìn thấy nhưng dài hơn bước sóng của tia X. Phổ của tia cực tím có thể chia ra thành 2 vùng tia: vùng tử ngoại gần (có bước sóng từ 380 - 200nm) và vùng tử ngoại xạ hay còn gọi là vùng tử ngoại chân không (có bước sóng từ 200 - 10nm).
