|
Students should be able to explain that all bodies (objects) emit radiation. |
|
(Physics only) Do only perfect black bodies (objects) emit radiation? |
|
|
|
(HT only) A body at constant temperature is absorbing radiation at the same rate as it is emitting radiation. |
|
(HT only) (Physics only) What is happening in terms of radiation and emission when a body is at a constant temperature? |
|
|
|
All bodies (objects), no matter what temperature, emit and absorb infrared radiation. |
|
(Physics only) At what temperature do all bodies (objects) emit and absorb infrared radiation? |
|
|
|
The hotter the body, the more infrared radiation it radiates in a given time. |
|
(Physics only) What is the relationship between temperature and radiation of infrared radiation? Write a conclusion for the results of the leslie cube demo |
|
|
|
Since a good absorber is also a good emitter, a perfect black body would be the best possible emitter. |
|
(Physics only) What colour object would be the best absorbed and emitter of radiation? Use the results of the leslie cube demo to apply to a range of different coloured objects.
Investigate how the colour of a surface affects how quickly an object will cool by the emission of infrared radiation. Use a Leslie cube or a ‘home-made’ version. |
|
|
|
Students should be able to explain that the intensity and wavelength distribution of any emission depends on the temperature of the body. |
|
(Physics only) What factors affect the intensity and wavelength distribution of emissions from a body (object)? |
|
|
|
A perfect black body is an object that absorbs all of the radiation incident on it. A black body does not reflect or transmit any radiation. |
|
(Physics only) What is a perfect black body (object)? Use results from practicals to answer the PLC questions on the relationship between bodies and radiation/emission on the website |
|
|
|
(HT only) The temperature of a body increases when the body absorbs radiation faster than it emits radiation. |
|
(HT only) (Physics only) What happens when the temperature of a body (object) increases? |
|
|
|
(HT only) The temperature of the Earth depends on many factors including: the rates of absorption and emission of radiation, reflection of radiation into space. |
|
(HT only) (Physics only) What factors can affect the temperature of the Earth? Use the phet animation to made links between radiation and the green house effect https://phet.colorado.edu/en/simulation/legacy/greenhouse
EW: Apply the ideas of radiation and emission to describe what factors can affect the temperature of the Earth |
|
|
|
(HT only) Students should be able to explain how the temperature of a body is related to the balance between incoming radiation absorbed and radiation emitted, using everyday examples to illustrate this balance, and the example of the factors which determine the temperature of the Earth. |
|
(HT only) (Physics only) Give an example of when the balance between incoming radiation absorbed and radiation emitted results in a constant temperature of a body (object) |
|
|
|
(HT only) Students should be able to use information, or draw/ interpret diagrams to show how radiation affects the temperature of the Earth's surface and atmosphere. |
|
(HT only) (Physics only) What affect to the temperature of the Earth's atmosphere would an increase in radiation absorbed have? GF: Explain how the particles in the atmosphere relate to emission and radiation, in your answer you should include the composition of the atmosphere, their structure, bonding and internal energy. |
