Parts and their functions

• Highest temperature (सबसे अधिक ताप) — Largest total emission (Stefan: ∝ T⁴) and the shortest peak wavelength.
• Intermediate temperature (मध्यम ताप) — Peak in between.
• Lowest temperature (सबसे कम ताप) — Peak at the longest wavelength (red-hot before white-hot).
• Wien’s displacement law (वीन का विस्थापन नियम) — λₘT = 2.9 × 10⁻³ m K. Sun: λₘ = 4753 Å ⇒ T ≈ 6060 K; moon: 14 µm ⇒ 200 K.
