In the absence of ozone layer, Which rays will enter into atmosphere? (1) Infrared (2) Visible (3) Ultraviolet (4) X-rays
by

1 Answer

Answer :

(3) Ultraviolet Explanation: The ozone layer is a layer in Earth's atmosphere containing relatively high concentrations of ozone (O3). The ozone layer absorbs 97-99% of the Sun's medium-frequency ultraviolet light (from about 200 nm to 315 nm wavelength), which potentially damages exposed life forms on Earth.
