Explanation:This problem can be solved by using Wien’s displacement law, which states that the peak wavelength and the temperature of a black body are inversely proportional to each other; mathematically:

where:

is the peak wavelength

T is the absolute temperature

is the Wien’s constant

In this problem, the temperature of the blackbody is:

T = 310 K

Therefore, solving for , we find the wavelength of the peak of the radiation emitted:

which can be rewritten in nanometers and microns, keeping in mind that:

we have:

Part b) of the problem is exactly the same as part a), since the temperature is the same, the wavelength is the same.
