Inverse of wien's displacement

In summary, the inverse of Wien's displacement law is the Wien's displacement constant (b), which is equal to the ratio of the speed of light (c) to the Wien's temperature (T). This constant is significant because it allows us to calculate the peak wavelength (λmax) of thermal radiation emitted by a blackbody at a given temperature (T). It is derived from the original Wien's displacement law and has a value of approximately 2.8977729 x 10^-3 mK. The inverse of Wien's displacement law is used in various practical applications, such as in the design of light bulbs and thermal imaging cameras, as well as in fields like astronomy and materials science.

Could I by any way find out average thermal retention of a blackbody that is irradiated with x rays? Since wavelength is inversely propotional to temp, in order to emit and absorb x rays it must be at a fairly high temperature I guess.

Any particular reason you think this should be the case?
 

1. What is the inverse of Wien's displacement law?

The inverse of Wien's displacement law is the Wien's displacement constant (b), which is equal to the ratio of the speed of light (c) to the Wien's temperature (T).

2. What is the significance of the inverse of Wien's displacement law?

The inverse of Wien's displacement law is significant because it allows us to calculate the peak wavelength (λmax) of thermal radiation emitted by a blackbody at a given temperature (T). This is important in understanding the distribution of energy emitted by a heated object and in various fields such as astronomy and materials science.

3. How is the inverse of Wien's displacement law derived?

The inverse of Wien's displacement law is derived from the original Wien's displacement law, which states that the product of the peak wavelength (λmax) and the temperature (T) of a blackbody is equal to a constant (c). By rearranging the equation, we get the inverse of Wien's displacement law as b = c/T.

4. What is the value of the inverse of Wien's displacement constant?

The value of the inverse of Wien's displacement constant is approximately 2.8977729 x 10^-3 mK. This value is derived from the speed of light (c = 2.99792458 x 10^8 m/s) and the Wien's temperature (T = 2.8977729 K).

5. How is the inverse of Wien's displacement law used in practical applications?

The inverse of Wien's displacement law is used in various practical applications, such as in the design of incandescent light bulbs, thermal imaging cameras, and in determining the temperature of stars and other celestial bodies. It is also used in materials science to study the properties of heated materials and in climate science to understand the thermal radiation emitted by the Earth and its atmosphere.
