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.

Expert Solution

Fundamentals

Wein's Law says that different objects at different temperatures emit different wavelength peaks. It is given as:
$λ_{m} T = b \dots \dots \dots (1)$
where,
$λ_{m}$ is the peak wavelength.
$T$ is the Temperature of the object.
$b$ is a constant, called the Wein's Displacement Constant $= 2.898 \times 10^{- 3} m K = 2898 μ m K$ .

This implies, the higher the temperature, the lower will be the peak.
