What form of electromagnetic radiation is emitted by low temperature objects like the human body?
Infrared radiation is invisible to us and emitted by the human body.
Most of the radiation emitted by a human body is in the form of?
Infrared
Why does amount of black body radiation emitted depend on temperature of object?
The hotter an object gets the faster its atoms vibrate.Vibration can be considered as a repeating cycle of accelerating, decelerating and then accelerating back again in the other direction.Accelerating charges radiate energyHence, vibrating atoms radiate energyHotter atoms vibrate more quickly so do more accelerating, so they emit more radiation!
What does radiate mean?
Radiation is the process by which energy is emitted from a source and propagated through the surrounding medium, or the energy involved in this process. Radiation consists of a flow of atomic or subatomic particles or of waves. Familiar examples are light (a form of electromagnetic radiation) and sound (a form of acoustic radiation). Both electromagnetic and acoustic radiation can be described as waves with a range of frequencies and intensities. Electromagnetic radiation is also often treated as discrete packets of energy, called photons. All matter is constantly bombarded by radiation from cosmic and terrestrial sources, and radioactive elements emit several types of radiation .
What is the maximum amount of radiation a human body can tolerate?
100 milliSieverts is the smallest radiation dose clearly linked to cancer. 1 Sievert is the smallest radiation dose required to induce radiation sickness. The average person absorbs 250 millirems over a lifetime.
What form of electromagnetic radiation is emitted by low temperature objects like the human body?
Infrared radiation is invisible to us and emitted by the human body.
Most of the radiation emitted by a human body is in the form of?
Infrared
What type of radiation emitted during a nuclear detonation and from fallout results in whole body exposure?
Gamma radiation
The wavelength of the radiation emitted by a body depends upon?
Temperature and emissivity of the body.
What is the violet shift?
a decrease in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect
Does your head emit radiation?
As long as you're alive, your head will emit heat radiation. (infrared) If you haven't been munching in on polonium etc, the number of other radiation emitted from your body is disposably small.
What is a thermogaph and how is it used?
Thermography it's also called thermal infrared imaging which you can view on a simple monitor the thermal image of a body or object.Since infrared radiation is emitted by all objects based on their temperatures based on the law of radiation.The amount of radiation emitted by an object increases with temperature, therefore thermography allows one to see variations in temperature as an image with the help of a thermograph. i hope I've been helpful.
At what temperature heat energy is converted to light energy?
Black-body radiation is the type of electromagnetic radiation within or surrounding a body in thermodynamic equilibrium with its environment, or emitted by a black body (an opaque and non-reflective body) held at constant, uniform temperature. The radiation has a specific spectrum and intensity that depends only on the temperature of the body.
What is the colour of a black body?
The term "black body," as related to "black body radiation," is a hold-over from the study of such light during the 1800s. BBR is emitted from any object that has a temperature. Such an object can be of any color.
What are three reasons radiation sickness symptoms vary?
Individual sensitivity Radiation dose absorbed type of radiationRadiation sickness varies based on the amount of expsure of radiation and how particular person's body reacts to the radiation poisoning. It also depends on how the radiation poisoning entered the body: Oral, inhalation or total body exposure.
How electromagnetic radaition produced?
well electromagnetic radiation is a combination of electrical and magnetic well electromagnetic radiation is a combination of electrical and magnetic
What was Wilhelm Wien most famous for?
Wilhelm Wien is German Physicist who received the Nobel Peace Prize for Physics for his law of displacement regarding radiation emitted by the black body.
