    Graduate Maximum frequency and temperature relation in Wien's displacement law

    Mgb thank you for your answer but I meant that how can I get it by formula. I have Planck spectrum formula SB law and wien law but i don't how how I can covert wavelength max to frequency max and state relationship omega max and temp. ?

    Graduate Maximum frequency and temperature relation in Wien's displacement law

    In Wien displacement law we know that wavelength max * Temperature = 2848 micrometer Kelvin How we can get the relationship between frequency max and Temperature ?
