P1 1 0.0 / 5 ? Physics1.1-1.9GCSEAQA Created by: BasitalCreated on: 12-02-17 17:14 What do all objects emit? Infrared radiation 1 of 12 What is Infrared radiation part of? Electromagnetic radiation 2 of 12 More infrared radiation is emitted if an object is? Hotter 3 of 12 Les infrared radiation is emitted if an object is? Colder 4 of 12 If an objects surroundings are colder than it, what will it do? Emit infrared radiation 5 of 12 If an objects surroundings are warmer than it, what will it do? Absorb infrared radiation 6 of 12 Why can infrared radiation travel through a vacuum (e.g space)? Because it does not require particles 7 of 12 What gases trap infrared radiation in the atmosphere? Water vapor, methane, and carbon dioxide 8 of 12 Short wavelength infrared radiation(+ light) from the sun can pass through what? The atmosphere 9 of 12 Why can't the infrared radiation pass back out through the atmosphere? It has a longer wavelength (because the objects emit this type of radiation) 10 of 12 What surfaces are the best absorbers and emitters of radiation? Black, Matt surfaces 11 of 12 What surfaces are bad reflectors of radiation? Black, Matt surfaces 12 of 12
