Which of the following waves are used to treatment of muscles ache?
- A Ủitraviolet
- B infrared
- C Microwave
- D X-rays
Answer & Solution
Correct Answer
(B) infrared
Step-by-step Solution
Detailed explanation
Infrared waves are electromagnetic waves with wavelengths longer than visible light but shorter than microwaves. They possess thermal energy, which is absorbed by the skin and underlying tissues, causing vasodilation and increased blood flow. This thermal effect is widely used…
