Question

Which of the following radiation is used to get relief from body aches?

  1. A. Infra-red radiation (Correct answer)
  2. B. UV radiation
  3. C. Visible radiation
  4. D. None of these

Correct Answer

Option A — Infra-red radiation

Detailed Solution & Explanation

The correct answer is Infra-red radiation.

Key Points

  • Infra-red (IR) radiation is used to get relief from body aches and muscle pain.
  • Because infra-red waves carry heat, they penetrate the skin and provide deep-heat therapy, which improves blood circulation, relaxes muscles and eases pain and stiffness — this is the principle behind IR lamps and heating pads used in physiotherapy.
  • The other radiations are unsuitable: Ultraviolet (UV) radiation is high-energy and can damage skin and cells; visible radiation is ordinary light and has no special pain-relieving heat effect.

Additional Information

  • infra-red lies just beyond the red end of the visible spectrum and is felt as warmth, which is exactly why it is used for therapeutic heating — making option (A) correct.
