  1. The way a body reacts to incident radiation depends upon the absorptive, reflectivity and transitivity. These are functions of the type of material and its color. For example black color metal would reflect more radiation than a black coloured plastic.

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.

When radiant heat strikes a surface there are three different possible outcomes?

When radiant heat strikes a surface, it can be absorbed, reflected, or transmitted. Absorption occurs when the surface takes in the radiant energy, increasing its temperature. Reflection happens when the radiant energy bounces off the surface without being absorbed, while transmission involves the radiant heat passing through the surface to the other side. The specific outcome depends on the properties of the surface material and the wavelength of the radiant heat.


When radiant heat strikes a surface there are three different possible outcomes. Identify each.?

When radiant heat strikes a surface, the three possible outcomes are absorption, reflection, and transmission. Absorption occurs when the surface takes in the radiant energy, converting it into heat. Reflection happens when the radiant heat bounces off the surface without being absorbed. Transmission refers to the radiant energy passing through the surface, depending on the material's transparency.

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.
