Answer:
B) [M⁰LT⁰K]
Explanation:
According to the Wien's displacement law the black-body radiation curve for different temperatures will be at peak at different wavelengths which are inversely proportional to the temperature.
According to the Wien's displacement law - λm = b/t
where b is the constant of proportionality and other is the Wien's constant.
Therefore, b will have the same dimensional formula as temperature. (T)
Thus, the dimensional formula will be - [M⁰LT⁰K]
