If the temp of hot body is increased by 50 the amount of radiation emitted is increased by?
The amount of radiation emitted by a hot body is directly proportional to the fourth power of its temperature (Stefan-Boltzmann law). Therefore, if the temperature of a hot body is increased by 50 units, the amount of radiation emitted will increase by a factor of (1+50/old temp)^4.
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.
Where is most of the radiation emitted that produces its black body spectrum?
Most of the radiation that produces a black body spectrum is emitted from the surface of the object itself. This radiation is a result of thermal vibrations of the atoms and molecules on the object's surface, which generate a continuous spectrum of electromagnetic radiation across various wavelengths.
What does the black body radiation graph represent and how does it relate to the concept of thermal radiation?
The black body radiation graph represents the intensity of radiation emitted by an object at different wavelengths. It relates to the concept of thermal radiation because it shows how an object's temperature affects the distribution of emitted radiation. As an object gets hotter, it emits more radiation at shorter wavelengths, which is known as thermal radiation.
What happens to total radiation from a black body if its absolute temperature is doubled?
The total radiation emitted by a black body is proportional to the fourth power of its absolute temperature according to Stefan-Boltzmann law. Therefore, if the absolute temperature of a black body is doubled, the total radiation emitted will increase by a factor of 16.
If the temp of hot body is increased by 50 the amount of radiation emitted is increased by?
The amount of radiation emitted by a hot body is directly proportional to the fourth power of its temperature (Stefan-Boltzmann law). Therefore, if the temperature of a hot body is increased by 50 units, the amount of radiation emitted will increase by a factor of (1+50/old temp)^4.
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.
What type of radiation emitted during a nuclear detonation and from fallout results in whole body exposure?
Gamma radiation
Where is most of the radiation emitted that produces its black body spectrum?
Most of the radiation that produces a black body spectrum is emitted from the surface of the object itself. This radiation is a result of thermal vibrations of the atoms and molecules on the object's surface, which generate a continuous spectrum of electromagnetic radiation across various wavelengths.
The wavelength of the radiation emitted by a body depends upon?
The temperature of the body. As the temperature of the body increases, the wavelength of the radiation emitted decreases, shifting towards shorter wavelengths. This relationship is described by Wien's displacement law.

What is it called when x-ray are initially absorbed by the body?
ionizing radiation

What are the factors does the heat emitted by a hot body depend?
The heat emitted by a hot body depends on its temperature, surface area, and emissivity. The Stefan-Boltzmann law states that the total amount of heat radiation emitted by a body is directly proportional to the fourth power of its absolute temperature.
Most of the radiation emitted by a human body is in the form of?
Infrared radiation. The human body emits infrared radiation as heat energy due to its normal metabolic processes. This type of radiation is not harmful and is commonly used in technologies such as thermal imaging.
Which type of body heat loss is characterized by heat transfer from the surface of one object to the surface of another object without actual contact?
Radiation is the type of body heat loss characterized by heat transfer from the surface of one object to the surface of another object without actual contact. This occurs through electromagnetic waves emitted by the warmer object and absorbed by the cooler object.
