⭐️ https://www.cognito.org/ ⭐️ *** 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. *** EXAM BOARD INFO *** AQA - Separate/triple science only IGCSE Edexcel - Not in your course Edexcel - Separate/triple science only OCR 21st Century - Separate/triple science only OCR Gateway - Separate/triple science only *** CHAPTERS *** 0:00 Introduction to Absorption and Emission 0:38 Temperature Changes due to Radiation 1:17 Electromagnetic Spectrum and Intensity 1:50 Intensity vs Wavelength Graphs 3:23 How Temperature Affects Emitted Radiation 4:16 Earth's Radiation Balance *** PLAYLISTS *** https://youtube.com/playlist?list=PLidqqIGKox7XPh1QacLRiKto_UlnRIEVh&si=orIUwL3o2jOoiYjT https://youtube.com/playlist?list=PLidqqIGKox7X5UFT-expKIuR-i-BN3Q1g&si=DcihOwUkd9oWbbdp https://youtube.com/playlist?list=PLidqqIGKox7WeOKVGHxcd69kKqtwrKl8W&si=Y8MsO-FK948jnxpS https://youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7&si=-7i5Iq7yOeJrhtu6 https://youtube.com/playlist?list=PLidqqIGKox7VKJD2WxRhoKaI6JGLVean8&si=NH_Q1ujhVgACM2FU #GCSE #Physics #study #revision #school #exam #AQA #OCR #Edexcel #IB #AP
