want it to start out on the floor because it wouldn't cool the room as effectively as if it starts from the ceiling, where it can cool the room as it falls. Radiation When you sit in front of a campfire, you are warmed by its heat. Hover your hand over a hot light bulb, and you'll feel the heat coming off it, even without touching it. Stand out in the sunshine, and you'll quickly get warmed by its rays. These examples illustrate our final mechanism of heat transfer, radiation. Radiation is when heat is transferred by electromagnetic waves, like radio waves, infrared waves, X-rays and even visible light. All objects both emit and absorb radiant energy - even you! Though, like everything else, some objects and substances are much better at this than others. Those that are good at emitting radiant energy, like the sun, are also very good at absorbing it. A radio antenna is designed to be a good absorber of radio waves, but that also means it's very good at emitting them. When it comes to radiant heat, much of what is produced on Earth comes from the earth itself. It absorbs radiant energy from the sun and then emits it back toward space. This radiant energy emitted by the earth is called terrestrial radiation, and it is what makes life possible. Like a big blanket, gases in the atmosphere trap terrestrial radiation on Earth and keep our planet nice and warm.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
