Подробнее о видео

⭐️ ⭐️

*** WHAT'S COVERED ***
1. Absorption and Emission of Electromagnetic Radiation
2. Effect of Temperature Differences
3. Intensity and Wavelength of Emitted Radiation
* Definition of radiation intensity.
* Relationship between the temperature of an object and the radiation it emits.
* How intensity vs. wavelength graphs show the distribution of emitted radiation.
* How increasing temperature increases the intensity of all wavelengths.
4. Earth's Energy Balance
* How Earth absorbs solar radiation and emits infrared radiation.
* The role of the atmosphere in reflecting, absorbing, and emitting radiation.
* How the balance between absorption and emission affects Earth's temperature.
* Factors contributing to the overall stability of Earth's temperature.
