BLACK BODY RADIATION
- When solids get hot, they give off radiation with a wide range of colours.
- As an example, when we heat a uniform colour, the changes keep happening as the temperature goes up.
- As the temperature rises, this colour change takes place from a lower-frequency region to a higher-frequency area.
- One example is that it often turns from red to blue. An ideal body that can both give off and take in all kinds of radiation is called a "black body." This kind of radiation is known as "black body radiation."
- So, we can say that the temperature affects the change in frequency for black body radiation.
- At a given temperature, the wavelength of radiation makes the strength of the radiation go up until it reaches its highest point, after which it goes down as the wavelength goes up again.
