Infra Rays: Sun or Human Body Wavelength?

In summary, the conversation is discussing the difference between the lengths of the infra-red wavelengths emitted by the sun and the human body. The term "infra" refers to infrared radiation, which has a fixed range of wavelengths regardless of the source. The question about which one produces more high-energy infrared rays is likely referring to shorter wavelength infrared, which is higher energy.

which one's infra rays wavelength are longer, sun or human body?

What do you mean by "infra" rays?? The only "infra" I know applied to wavelength is infrared radiation which has a fixed range of wavelengths no matter where it comes from.

infra-red rays

Waves are basically classified on the basis of wavelength ( or frequency ). Infra-red rays is the name for the rays having a particular range for wavelengths. So, it doesn't matter what the source of the rays is. If the wavelength falls in the range, they are called infrared rays.

This sounds like one of those "flawed" questions that come from a lower-level (elementary or junior high) textbooks. I'm guessing that what the question is getting at is:
"which produces more high-energy infrared rays, the sun or a human body." I'm sure you could guess which one.

THen, what you need to know is that "high energy" infrared is "shorter wavelength" infra red. Take it from there.
 

Related to Infra Rays: Sun or Human Body Wavelength?

1. What are Infra Rays?

Infra rays, also known as infrared radiation, are a type of electromagnetic radiation with a longer wavelength than visible light. They are invisible to the human eye but can be felt as heat.

2. How are Infra Rays produced by the Sun?

The Sun produces infra rays as a form of heat through nuclear fusion reactions in its core. These rays travel through space and reach Earth, where they contribute to the planet's overall temperature and climate.

3. What is the wavelength range of Infra Rays in the Sun?

The wavelength range of infra rays produced by the Sun is typically between 750 nanometers to 1 millimeter.

4. Can Infra Rays be harmful to the human body?

In general, infra rays are not harmful to the human body. However, excessive exposure to high levels of infrared radiation can cause burns or damage to the skin and eyes. It is important to limit exposure and take precautions when working with infrared sources.

5. How does the human body emit Infra Rays?

The human body emits infra rays through the process of thermoregulation, where heat is radiated from the body to maintain a constant internal temperature. The skin and internal organs also emit infrared radiation as a byproduct of metabolic processes.
