We consider the radiation emitted by the human body. Which one of the following statement is true?

Options

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

Correct answer

A. The radiation emitted is in the infrared region

Step-by-step solution

Every body at all times, at all temperature emit radiation which fall in the infrared region.
