The incorrect statement is the third one:
"Ultraviolet light waves can be used to sterilize items such as medical equipment."
Why: UV-C (around 254 nm) is widely used for disinfection of air, water and surfaces, but it has very limited penetration, is blocked by shadowing or opaque materials, and is not reliably sporicidal. Therefore it is typically used for disinfection, not for sterilization of critical medical instruments (which require autoclaving, ethylene oxide, gamma/e-beam/X‑ray irradiation, etc.).
