Question

when caring for wounds, doctors need to make sure wounds are not infected by bacteria. which electromagnetic wave would doctors most likely use for this purpose?
gamma rays
ultraviolet waves
visible light
x - rays

Explanation:

Ultraviolet (UV) waves have germicidal properties. They can disrupt the DNA of bacteria, preventing them from reproducing and thus helping to prevent wound infections. Gamma rays are too harmful for regular wound - care use. Visible light does not have significant antibacterial effects for this purpose. X - rays are mainly used for imaging bones and internal structures, not for disinfecting wounds.

ultraviolet waves
