The disinfection process that utilizes a specific wavelength to kill or inactivate microbes is **UV light**.

### Explanation
UV light, particularly UV-C light, has wavelengths between 200 to 280 nanometers and is known for its effective germicidal properties. When microbes are exposed to UV light, their DNA absorbs the energy, leading to the formation of pyrimidine dimers, which disrupts their ability to replicate and effectively inactivates them. This method is widely used in water treatment facilities, air purification systems, and surface sterilization.

In contrast, ozone and chlorination involve chemical reactions to disinfect, rather than relying solely on a specific wavelength of light. Therefore, UV light is the correct choice for disinfection through wavelength exposure.
