Understanding Radiation Emitted by the Human Body
The human body emits radiation primarily in the infrared region, which is crucial for thermoregulation and heat dissipation. Here’s a detailed explanation of why option 'B' is correct:
Infrared Radiation Emission
- The human body maintains a core temperature around 37 degrees Celsius (98.6 degrees Fahrenheit).
- To maintain this temperature, the body continuously emits infrared radiation, which is a form of electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves.
- This emission occurs due to the thermal energy produced by metabolic processes within the body.
Characteristics of Infrared Radiation
- Infrared radiation is not visible to the human eye, which is why it may not be perceived, but it can be felt as heat.
- The wavelengths of infrared radiation emitted by the body typically range from 3 to 14 micrometers.
Why Other Options are Incorrect
- Option A: The body does not emit ultraviolet radiation; instead, it emits infrared radiation.
- Option C: The body emits radiation continuously, day and night, regardless of the time.
- Option D: Radiation emission is not dependent on seasons; it occurs consistently throughout the year.
Conclusion
In summary, the correct answer is option 'B' because the human body primarily emits radiation in the infrared region, essential for temperature regulation and not limited by time or season. Understanding this emission is vital for areas like health, safety, and technology applications, such as thermal imaging.
