Radiation exists in the atmosphere, the ground, the water and even within our own bodies. It's called natural background radiation, and it's perfectly safe. Radiation affects your body by depositing energy in your tissues, which can cause cell damage. In some cases, this won't cause any...
This chapter starts with simple concepts of how incident radiation in combination with atmospheric scattering and absorption determines the brightness and color of clouds, the sky, and haze. The concept and geometry of radiance is presented along with how radiant energy is transmitted through the ...
Consider the electromagnetic radiation inside a kiln, with a volume of 1 m and a temperature of 1500 K. (a) What is the total energy of this radiation? (b) Sketch the spectrum of the radiation as a How do you determine the wavelength and frequency of electroma...
The multi-purpose of publicizing a scientific consensus includes a communicative strategy by which scientific institutions accommodate the weighty social a
Why does air rise at the equator? How do clouds and precipitation in the atmosphere develop? Please describe the structure of a hurricane, and how they work. Include a discussion of how energy is transferred, from the warm ocean water, up to the sky. ...
Whenever any object has a temperature above absolute zero (-273ºC), it will emit infrared radiation. The total wavelength of infrared is about 0.75μm (750nm) to 1,000 micrometers (μm). It is then divided into three types of wavelengths based on their energy content: near-infrared ...
The rest of it ends up getting absorbed when it hits certain things in the atmosphere, such as carbon dioxide, methane gas and water vapor. After these components in our atmosphere absorb all this heat, they emit energy (also in the form of heat). The heat that doesn't make it out ...
Objects entering the Earth's atmosphere do so at a speed at least equal to the escape velocity of the Earth. After an object enters the atmosphere it is slowed by friction with the air, which also causes it to heat and glow. The more massive the incoming object, the less it is slowed...
Your house may seem like a big complex space with lots going on inside in but, from the point of view of physics, it's exactly the same as a camp fire in the middle of vast, cold surroundings: it constantly radiates heat into the atmosphere.The more heat escapes from your home, the...
Thesunemits thermal radiation that travels towardEarth. When solar radiation reaches thick clouds in Earth's atmosphere, those clouds can reflect the radiation out into space, keeping the planet cool. But when the radiation does reach Earth's surface, the planet itself reflects solar radiation out...
