Stick Infrared Emitters
I am trying to explain this to my daughter and I am stuck.?
1. All objects, at any temperature, emit radiant energy. Not only hot objects like the sun but also Earth—including its polar ice caps—continually emit energy.
2. Hotter objects radiate more total energy per unit area than colder objects do.
3. The hottest radiating bodies produce the shortest wavelengths of maximum radiation. For example, the sun, with a surface temperature of nearly 6000°C radiates maximum energy at 0.5 micrometers, which is in the visible range. The maximum radiation for Earth occurs at a wavelength of 10 micrometers, well within the infrared range.
4. Objects that are good absorbers of radiation are good emitters as well. Gases are selective absorbers and radiators. The atmosphere does not absorb certain wavelengths of radiation, but ita= good absorber of other wavelengths.
Write a paragraph that gives real-life examples that demonstrate TWO of the four laws governing radiation discussed above.
Nice try but sounds like homework to me, (I’ve been there). At least try to answer it your self so that you actually learn the material.
