Homework Statement
The peak intensity of light from the sun occurs at a wavelength 500nm. Astronomers discover a nearby star X which is the same size and mass as the sun, but has a peak wavelength of half this value. Is X hotter or colder than the sun and by how much?[/B]
Homework Equations
Wiens law
Max= c/t where c is a constant equal to 2897 and t is the temp in kelvin[/B]
The Attempt at a Solution
I know I'm suppose to divide when trying to find out the peak wavelength, but it's given so I'm assuming I have to multiply in order to find the temp except I can't figure out the equation.
Any help would be appreciated. [/B]
