🔹 अध्याय ११: पदार्थाचे ऊष्मीय गुणधर्म

🔸 ऊष्मा विरुद्ध तापमान

🔥 ऊष्मा (Heat): तापमानातील फरकामुळे होणारी उर्जेची देवाणघेवाण

🌡️ तापमान (Temperature): कणांच्या सरासरी गतिज ऊर्जेचे माप

🔸 ऊष्मीय प्रसरण (Thermal Expansion)

📏 रेखीय प्रसरण (Linear Expansion):
ΔL = αL₀ΔT
(L₀: मूळ लांबी, α: रेखीय प्रसरण गुणांक, ΔT: तापमानातील बदल)

📐 क्षेत्रफळ प्रसरण (Area Expansion):
ΔA = βA₀ΔT
(A₀: मूळ क्षेत्रफळ, β: क्षेत्रफळ प्रसरण गुणांक)

🔲 घनफळ प्रसरण (Volume Expansion):
ΔV = γV₀ΔT
(V₀: मूळ घनफळ, γ: घनफळ प्रसरण गुणांक)

🧪 घन, द्रव व वायू यांचे प्रसरण वेगवेगळे असते.

🔸 ऊष्मा धारिता व विशिष्ट ऊष्मा (Heat Capacity & Specific Heat)

🌡️ ऊष्मा धारिता (Heat Capacity):
C = Q/ΔT

🌡️ विशिष्ट ऊष्मा (Specific Heat):
c = Q/mΔT
(Q: दिलेली ऊष्मा, m: वस्तुमान, ΔT: तापमान बदल)

📌 Wave Optics In One Short

→ Wave optics explains the nature of light in terms of wave behavior.

→ Important concepts: Interference, Diffraction, and Polarization.

→ Interference: Superposition of two light waves to form constructive or destructive interference.

→ Young’s Double Slit Experiment (YDSE): Demonstrates interference pattern due to coherent sources.

→ Diffraction: Bending of light around obstacles; single-slit diffraction pattern is observed.

→ Polarization: Light waves oscillate in a single plane; used in sunglasses and 3D glasses.
