Question

the graph shows the distribution of energy emitted by a star. which is the best conclusion to draw about the star? it has a lower temperature than the sun because its peak wavelength is longer than the suns. it has a lower temperature than the sun because its peak wavelength is shorter than the suns. it has a higher temperature than the sun because its peak wavelength is longer than the suns. it has a higher temperature than the sun because its peak wavelength is shorter than the suns.

Explanation:

According to Wien's displacement law, the peak - wavelength of the radiation emitted by a black - body (a good approximation for stars) is inversely proportional to its temperature ($\lambda_{max}T = b$, where $b$ is Wien's displacement constant). A longer peak - wavelength means a lower temperature. If the star's peak wavelength is longer than the Sun's, it has a lower temperature.

Answer:

It has a lower temperature than the Sun because its peak wavelength is longer than the Sun's.
