## What are the dimensions of Stefen Boltzmann constant?

The value of Stefan Boltzmann constant is universally accepted and given in SI units as- Stefan Boltzmann Constant σ = 5.670367 (13) × 10 -8 W⋅m -2.K -4 The dimensional formula is [M] 1 [T] -3 [Θ] -4 It can also be expressed in other units as well.

### What are the dimensions of Stefan-Boltzmann constant σ?

The dimensions of Stefan-Boltzmann constant σ can be written in terms of Planck's constant h, Boltzmann constant kB and the speed of light c as σ = hα kBβ cγ.

### What is Stefan-Boltzmann law in astronomy?

Stefan-Boltzmann Law. If the radius R of the star is given in meters and the temperature is in Kelvin, the numerical constant σ = 5.67 x 10 -8 and the luminosity will come out in Watts. (Unsurprisingly, σ is called the Stefan-Boltzmann constant.)

### What is the dimensional formula of Stefan's constant?

The dimensional formula of Stefan's constant is MT –3 K –4 ML 2 T 2 K –4 ML 2 T –2

### What is the formula for the Stefan–Boltzmann law?

. P = A j ⋆ = A ε σ T 4 . {\displaystyle P=Aj^ {\star }=A\varepsilon \sigma T^ {4}.} Wavelength- and subwavelength-scale particles, metamaterials, and other nanostructures are not subject to ray-optical limits and may be designed to exceed the Stefan–Boltzmann law.
