We consider the radiation emitted by the human body, which of the following statements is true?
- A The radiation is emitted only during the day.
- B The radiation is emitted during the summers and absorbed during the winters.
- C The radiation emitted lies in the ultraviulet region and hence is not visible.
- D The radiation emitted is in the infrared region.
Answer & Solution
Correct Answer
(D) The radiation emitted is in the infrared region.
Step-by-step Solution
