Radiation and Heat
Radiation is related to heat since radiation is one of three ways that heat transfer occurs. Unlike conduction and convection radiation does not rely on the movement of particles to transfer heat. Energy transferred from its source by radiation is called radiant energy. Heat is only one type of radiant energy. It is transferred by IF rays (Infrared rays). An example of radiant energy is a simple dashboard. Have you ever gone to a store in the summer and go into your car afterwards and noticed its really hot and the dashboard is incredibly hot. This is because of radiant energy going from the suns rays and into your car via window. The reason why the dashboard is hotter than the area around it. Is because of the material it is made of and the color it is. If it is black in color or a dark color like this it will absorb more light energy wavelengths than white which reflects most wavelengths. Look at other pages to learn more about radiation.
