From a nearby heater (Plato i suspect)
Infra Red or heat
The sun is the best example of radiation because, of the three processes of heat transfer (conduction, convection, radiation), the sun only radiates heat energy.Conduction occurs through matter, and we are separated from the sun by an absence of matter (vacuum).Convection is the movement of a fluid, carrying heat. Although there is a solar wind, it is very very tenuous - a vacuum.You can step outside and feel the sun's radiation (infrared) on your skin, see the light with your eyes.
Radiation is when heat shoots out like a ray, so all the examples given show radiation.
Heating a pot over a stove is an example of conduction heat. However, roasting a marshmallow near a heat source such as a campfire is an example of radiation heat.
energy that is radiated or transmitted in the form of rays or waves or particles. in other words, it is heat that is tranfered through air, rather that through solids. example: the sun heating earth.
Radiation and sense of touch which is the receptors of our hands feeling things close to us
Heat transfer through radiation is probably best illustrated by the warming of the earth by the sun. Electromagnetic energy from the sun in the form of light travels through the vacuum of space to reach the earth and warm us.
The fireplace's heat is an example of radiation.
The earth receives heat from the sun as radiation
A campfire is an example of radiation because heat is being emitted from the fire. The heat is what is being radiated, and the heat is a characteristic of the campfire.

For example, you are touching something that feels like you are putting your hands into something very ice cold. That is how you can lose heat from your body.
Is it radiation when put hands above fire.
Radiation heat is heat that comes directly off its source in a straight line. For example heat coming off the sun.
Prime example of radiation in our every day life is the heat we get from the sun (mostly radiation heat)
Some examples of energy transfer by radiation are: 1) standing in sunlight and feeling the heat on your face (UV radiation is entering the skin, converting to infrared radiation, and is absorbed by your tissues); 2) sitting near a fire and feeling the heat on your skin (infrared radiation transfer); 3) chemical reactions that occur due to a source of radioactivity (gamma radiation, being high-energy photons, travel from the radioactive source through the air into the target sample, and induce chemical reactions
