Ultraviolet waves are primarily utilized in which field?

• A. Photography
• B. Medicine
• C. Telecommunications
• D. Heating

Answer: (B)

Ultraviolet waves are primarily utilized in medicine due to their ability to kill bacteria and viruses, making them effective for sterilization and disinfection processes. This application is particularly important in areas such as surgical procedures and water purification systems. Furthermore, ultraviolet light is used in phototherapy, which helps treat certain skin conditions like psoriasis and eczema by promoting healing through controlled exposure to UV radiation.

In contrast, while there may be some overlap in areas like photography, telecommunications, and heating, these fields do not primarily rely on ultraviolet waves. Photography commonly uses visible light rather than UV, telecommunications typically involve radio and microwaves, and heating applications often utilize infrared waves instead. Thus, the medical field is where ultraviolet waves are most prominently and beneficially applied.
