What Radiation emitted by a body that absorbed it first?
The radiation emitted by a body that absorbed it first is known as re-emitted or secondary radiation. This occurs when absorbed energy is re-radiated by the object in a different form such as heat or light.
What happens to radiant heat when it falls on a body what does the absorption of radiant heat by a body depend on?
When radiant heat falls on a body, it can be absorbed, reflected, or transmitted through the body. The absorption of radiant heat by a body depends on factors such as the material's surface properties, color, texture, and temperature. Materials with dark colors and matte surfaces tend to absorb more radiant heat compared to light-colored and shiny surfaces.
Is absorbed radiation re emitted as energy?
Yes, absorbed radiation can be re-emitted as energy in the form of electromagnetic radiation or heat. This phenomenon is known as re-emission or re-radiation. The amount and wavelength of the re-emitted radiation depend on the properties of the absorbing material.
What electromagnetic wave human body emitted?
The human body naturally emits low levels of infrared radiation, also known as heat energy. This is due to the body's heat production through metabolic processes.
What is the primary mode of heat loss?
The primary mode of heat loss in humans is through radiation, where body heat is emitted in the form of infrared radiation. Other modes of heat loss include conduction, convection, and evaporation.

Is heat emitted by the body at 200 celsius is twice the heat emitted by the body at 100 celsius?
Not at all. First of all, 200 Celsius is not double 100 Celsius. To make this kind of comparisons, you have to use an absolute scale, i.e., Kelvin. 200 Celsius = 473K; 100 Celsius = 373K, so that is only about a 27% increase. Second, the energy emitted by a hot body is (roughly?) proportional to the 4th. power of the temperature. Raising the ratio to the fourth power gives you a factor of about 2.59 - the hotter body will radiate 2.59 times as much heat energy as the cooler body.
How do you mesure extreme temperatures?
Depending on the heat emitted by a body, the colour of the body varies. by mapping the colour of a body to the standard scales, the temperature of the body can be determined. The temperature of sun is determined in this manner.
What is the primary mode of heat loss?
The primary mode of heat loss in humans is through radiation, where body heat is emitted in the form of infrared radiation. Other modes of heat loss include conduction, convection, and evaporation.
What three ways do you lose heat?
You can lose heat through convection, where heat is transferred through air or water currents; conduction, when heat is transferred through direct contact with a colder object; and radiation, when heat is emitted as infrared radiation from your body.
How much heat does a human body produce and what factors can affect this production?
The human body produces about 100 watts of heat at rest. Factors that can affect this heat production include physical activity, metabolism, environmental temperature, and illness.
Do mosquitoes like fire?
Mosquitoes are not attracted to fire. They are more attracted to body heat, carbon dioxide, and certain scents emitted by humans.
Do mosquitos have an attraction to fire?
Mosquitoes are not attracted to fire. They are more attracted to body heat, carbon dioxide, and certain scents emitted by humans.
What are some examples of infared rays?
Examples of infrared rays include heat radiation from a fire, body heat emitted by humans and animals, and infrared lamps used in therapy. Infrared rays are also emitted by the sun and can be used in technologies like infrared cameras and communication devices.
