Worked Solution & Example Answer:Which statement about infra red radiation is correct? A - OCR Gateway - GCSE Physics - Question 3 - 2021 - Paper 1
Step 1
B. Infra red is emitted by humans.
Answer
Infrared radiation is indeed emitted by humans as a result of body heat. This electromagnetic radiation is a form of energy that is commonly associated with thermal radiation. The human body is continuously emitting this type of radiation due to its temperature, which is typically around 37°C (98.6°F) in a resting state. Therefore, option B is the correct statement regarding infra red radiation.
