The Sun emits infrared radiation, as well as a broad spectrum of other rays of electromagnetic radiation. It is the infrared band, that just beyond (and just longer in wavelength) what we see as the color red, which reacts with matter to increase its temperature. Infrared from sunlight heats the Earth's surface and atmosphere.
The warmth of sunlight is an effect of the absorption of the electromagnetic radiation by a surface. If an object were totally transparent or totally reflective, the sunlight would not warm it up.
Because they don't have enough energy (or a short enough wavelength) to knock electrons off of atoms (ionization).
Joule showed the heating effect due to the resistence of wire which cary the current.
negative effect of science .. with picture
Disadvantages of the heating effect of electric currents are: short circuits, house fires, and explosions. Advantages of the heating effect of electric currents are: electric light, toasting food, and keeping a room warm.
ultraviolet rays
by the radiation in the filament it throw out heat . this way the bulb demonstrates the heating effect. :D
The warmth of sunlight is an effect of the absorption of the electromagnetic radiation by a surface. If an object were totally transparent or totally reflective, the sunlight would not warm it up.
The Greenhouse Effect.
The Greenhouse Effect.
The Greenhouse Effect.
The trapping by the greenhouse gases of the long wavelength radiation (infrared) leads to more heating and a higher resultant temperature.
The heating of the lower layer of the atmosphere from radiation absorbed by certain heat-absorbing gases is called the greenhouse effect. Water vapor and carbon dioxide are the two most important heat absorbing gases in the lower atmosphere.
The trapping of heat by the Earth's atmosphere is called the greenhouse effect. During the greenhouse effect, radiation becomes entrapped which results in the heating of the Earth.
the green house effect
Space is cold!Sunlight is very intense in space, causing rapid heating of exposed surfaces. Spacesuits are white to reduce this solar heating effect, but it doesn't eliminate it.
The trapping of heat by the Earth's atmosphere is called the greenhouse effect. During the greenhouse effect, radiation becomes entrapped which results in the heating of the Earth.
