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.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
