The radiation emitted by the sun is brightest at a wavelength of about 5000 Å (1 Å is 10^-10 m).At what wavelength would the Sun be brightest if its temperature were doubled? A)2500 Å B)5000 Å C)10,000 Å D)20,000 Å

The wavelength at which a black body (like the sun) emits radiation most strongly is inversely proportional to its temperature, according to Wien's displacement law. If the temperature is doubled, the peak emission wavelength is halved. Therefore, if the sun's temperature were doubled, the wavelength at which it is brightest would be halved from 5000 Å to 2500 Å.
