Question

The dimensions of Wien's constant are

• A. $\left[M{L}^{0}TK\right]$
• B. $\left[M^{0}L{T}^{0}K\right]$
• C. $\left[M^0{L}^{0}TK\right]$
• D. $\left[MLTK\right]$4

Answer 1

Answer: (B)

$\left[M^{0}L{T}^{0}K\right]$

Here ${\lambda }_m$ is maximum wavelength at temperature $T$
Wien's constant $b$ is given as $b={\lambda }_{m}T=LK=\left[M^0{L}^1{T}^0{K}^1\right]$
