When there is depletion of ozone in the stratosphere, the wavelength of radiation striking the earth's surface will be:
- a)10-7 m

When there is depletion of ozone in the stratosphere, the wavelength of radiation striking the earth's surface will be 10-10 m. UV radiation has a shorter wavelength than visible light, and as ozone depletion allows more UV radiation to reach the Earth's surface, the wavelength of radiation striking the Earth's surface will be shorter.

Understanding Ozone Depletion
Ozone in the stratosphere plays a crucial role in absorbing harmful ultraviolet (UV) radiation from the sun. When there is a depletion of ozone, more UV radiation reaches the Earth's surface.
Impact of Ozone Depletion
- Ozone absorbs UV radiation primarily in the wavelengths between 200 nm and 300 nm (10^-7 m to 10^-8 m).
- With reduced ozone, higher-energy UV radiation (with shorter wavelengths) can penetrate the atmosphere.
Examining the Wavelengths
- 10^-7 m (100 nm) - This range is still within the UV spectrum.
- 10^-10 m (0.1 nm) - This is in the X-ray range, which is not significantly impacted by ozone.
- 10^-2 m (1 cm) - This is in the microwave range and does not relate to UV radiation.
- 100 m - This is a radio wave range, far removed from UV impacts.
Conclusion
Given the context of ozone's protective role against UV radiation, the correct answer is 10^-10 m. This wavelength is more likely to increase at the Earth's surface due to the depletion of ozone, allowing more higher-energy radiation to reach us.
Thus, the answer is option b) 10^-10 m, indicating an increase in harmful radiation resulting from ozone layer depletion.
