Question 11: each part = [5 pts]Question 13: each part = [5 pts]Question 12: [5 pts]Question 14: [5 pts]Using the blackbody radiation calculator, at what wavelength does a temperature of 310 K radiate? Use the calculator to express in11.(a) nanometers &microns: nm[round to whole number](b) μm[round to 2decimals]12.Using the Planck Curve for Blackbody Radiation, the peak of the curve for 310 K is at what wavelength? μm

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.
