Answer: The correct answer is ultraviolet wave.
Step-by-step explanation:
Electromagnetic wave is the wave in which both electric field and magnetic field are perpendicular to each other to the direction of the motion of the wave.
For example, Ultraviolet wave.
Ultraviolet wave is very harmful wave. The exposure of this wave can cause skin cancer.
This radiation has been used for disinfectant. Ultraviolet wave is used by a lab technician to clean medical instruments that have been exposed to bacteria. Bacteria contain DNA which is vulnerable to ultraviolet radiation. This radiation inactivates or kills the microbes.
Therefore, the correct answer is ultraviolet wave.
