Practise identifying UV radiation as the harmful solar radiation absorbed by stratospheric ozone and explaining why wavelength matters.
How this is tested
- state UV or shortwave UV as the radiation absorbed by the stratospheric ozone layer
- link shorter wavelength and higher frequency UV to greater biological damage
