Wien's law
λ_max T = b
Where: T = time period (s) / temperature (K) / tension (N), b = b, λₘₐₓ = λₘₐₓ
Solved example
Given: b = 7, lamda_max = 5
Find: T (time period (s) / temperature (K) / tension (N))
- Formula: T·λₘₐₓ = b
- Rearranged for T: T = b/λₘₐₓ
- Substitute the values: T = 7/5
- Result: T = 1.4
Answer: T = 1.4

Frequently asked questions
What is the formula for Wien's law?
The formula is λ_max T = b, where T = time period (s) / temperature (K) / tension (N), b = b, λₘₐₓ = λₘₐₓ.
What is Wien's law when b = 7, lamda_max = 5?
T = 1.4. Substitute the values into λ_max T = b and simplify.
