The incorrect statement is:
"Ultraviolet light waves can be used to sterilize items such as medical equipment."
Why: UV-C (germicidal UV) is widely used to disinfect air, surfaces and water by inactivating microbes, but it has poor penetration, is blocked by shadows/soiling, and is much less reliable against resistant spores. Because of those limits, UV is generally used for disinfection rather than as a validated sterilization method for medical instruments. Sterilization of instruments is normally done by autoclaving, ethylene oxide, or ionizing radiation (gamma/e‑beam; industrial X‑ray sterilization also exists but is less common). The other three statements are essentially correct.
