Question 3 please

1. Plot ipeak Vs 1/T using the scatter plot as you did in the previous experiment. Make a
linear fit of the data (add a linear trendline) by selecting the intercept at zero. Display an
equation of this fit on the chart. What value of “b" do you get? (Attach your plot to this
lab report).
b =
um-K
2. Calculate the discrepancy error, |b - 2898|/ 2898 × 100% and comment about your
finding. Does it agree with the theoretical value?
3. Using your value of b and the Wien's Displacement equation, predict the surface
temperature of a neutron star whose peak wavelength is observed in the x-ray region of
A peak = 0.001 µm.
T =
K
4. The normal human body temperature is T= 310 K. At what wavelength would humans
emit the blackbody radiation? What region of the electromagnetic spectrum does it
correspond to?
hum
um.
5. Can you now explain why blue stars hotter than the red stars?
