—Wien’s displacement law λmax ∝ 1 / T to estimate the peak surface

recall and use Wien’s displacement law λmax ∝ 1 / T to estimate the peak surface temperature of a star.

Use —wien’s displacement law λmax ∝ 1 / t to estimate the peak surface to connect the rule to the data and decision in the question.

This matters because —wien’s displacement law λmax ∝ 1 / t to estimate the peak surface determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —wien’s displacement law λmax ∝ 1 / t to estimate the peak surface to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Wien’s displacement law λmax ∝ 1 / T to estimate the peak surface is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
