We consider the radiation emitted by the human body. Which of the following statements is true ?
- A The radiation is emitted during the summers and absorbed during the winters
- B The radiation emitted lies in the ultraviolet region and hence is not visible
- C The radiation emitted is in the infrared region
- D The radiation is emitted only during the day
Answer & Solution
Correct Answer
(C) The radiation emitted is in the infrared region
Step-by-step Solution
Detailed explanation
The heat radiation emitted by the human body is the infrared radiation. Their wavelength is of the order of \(7.9 \times 10^{-7} \mathrm{~m}\) to \(10^{-3} \mathrm{~m}\) which is of cource the range of infrared region.
Hence, human body emits radiation in infrared region.
Hence, human body emits radiation in infrared region.
