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.
What happens to arterioles when the body temperature falls?
When the body temperature falls, arterioles constrict in order to reduce blood flow to the skin and maintain body heat. This vasoconstriction helps to conserve warmth by directing more blood flow to vital organs and minimizing heat loss through the skin.
What is the difference between radiant heat and convection heat?
In convection heat you heat the air first and then use the hot air to heat yourself. In radiant heat, the energy must be radiated directly from the heat element to your body. Note that radiant is much more directional.
How can you tell that you are absorbing radiant energy from the sun?
You can tell that you are absorbing radiant energy from the sun if you feel warmth on your skin or if you notice a change in your body temperature when exposed to sunlight. This is because the sun's energy is being converted into heat as it is absorbed by your body.
The warmth you feel when standing beneath a heat lamp is an example of what?
The warmth you feel when standing beneath a heat lamp is an example of radiant heat transfer. The heat lamp emits infrared radiation, which travels in waves and is absorbed by your body, resulting in the sensation of warmth.

What exactly is radiant energy?
the process by which heat is transfer from one body to another {in air} while using no medium is known as radiation or radiant energy.
In what form does radiant heat transmit?
Radiant heat transmits in the form of waves.

What is a body of gas that gives off tremendous amount of radiant energy in the form of light and heat?
A star is a body of gas that gives off tremendous amounts of radiant energy in the form of light and heat through nuclear fusion reactions in its core.
What happens to temperature of the house as the suns radiant energy touches it?
The temperature of the house increases as the sun's radiant energy touches it. This is because the house absorbs the energy from the sun, converting it into heat.
What matches with radiant heat on the electromagnetic spectrum?
Radiant heat corresponds to infrared radiation on the electromagnetic spectrum. This type of heat is emitted by warm objects and can be detected as heat by our skin or specialized sensors. Infrared radiation is commonly used in technologies like infrared heaters and thermal cameras.
What happens to most of the sun radiant energy?
Most of the Sun's radiant energy is absorbed by Earth's atmosphere and surface, where it is then converted into heat. Some of it is reflected back into space by clouds and the Earth's surface.
What happens to the temperature of a house as the suns radiant energy touches it?
The temperature of the house increases as the sun's radiant energy is absorbed by the building materials. This happens because the materials absorb the sun's energy and convert it into heat, raising the temperature inside the house.
