The SI unit of Stefan's constant is
Correct answer: B. Wm²K⁻⁴
- A. Wm⁻²K²
- B. Wm²K⁻⁴
- C. Wm⁻⁴K⁴
- D. Wm⁻⁴K⁻⁴
Explanation
tefan's constant (σ) is expressed in the SI unit of Wm2K−4Wm2K−4.Incorrect Options and Explanations: (a) Wm⁻²K² - This unit does not represent Stefan's constant. (c) Wm⁻⁴K⁴ - This unit does not represent Stefan's constant. (d) Wm⁻⁴K⁻⁴ - This unit does not represent Stefan's constant.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
