We consider the radiation emitted by the human body, which of the following statements is true?

Options

  1. AThe radiation is emitted only during the day.
  2. BThe radiation is emitted during the summers and absorbed during the winters.
  3. CThe radiation emitted lies in the ultraviulet region and hence is not visible.
  4. DThe radiation emitted is in the infrared region.

Correct answer

D. The radiation emitted is in the infrared region.

Step-by-step solution

Every body at all times, at all temperatures emits radiation. The radiation emitted by the human body is in the infrared region.
