response to UV response to UV-B response to UV-B light stimulus response to UV-B radiation stimulus response to medium wave ultraviolet radiation stimulus response to UVB radiation stimulus Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a UV-B radiation stimulus. UV-B radiation (UV-B light) spans the wavelengths 280 to 315 nm. response to UVB light stimulus response to medium wave ultraviolet light stimulus biological_process GO:0010224
