Question

The surface temperature of a star is predicted from its color usinga) Stefan's law of radiation b) Kirchoff's law of radiationc) Wein's displacement law d) Newton's law of cooling​

Answer 1

Answer:

c) Weins displacement law

Explanation:

The wavelength corresponding to the maximum energy of radiation is related to the temperature of the radiating body by the relation: λT=const

Answer 2

The star's higher temperature is predicted by its color:

c) Wien’s displacement law

• The law of Wien or the law of Wien emigration, named after Wilhelm Wien was discovered in 1893.

• Wien's migration law states that the curve of the black body radiation of different temperatures will reach the height of the different wavelengths corresponding to the opposite temperature.

• Named after German physicist Wilhelm Wien in honor of his remarkable contribution to the definition of the dark rays of the body.

• Wien law gives us the relationship between the light wavelength associated with the maximum intensity and the total temperature of the object.

• The spectral density of the output is determined by the length of each wave at a given temperature using Planck's law of black body radiation.

• The relationship between total released energy and total temperature is defined by Stefan-Boltzmann's law.
