The unit of Wien's constant b is
Options
- AWm ⁻² ~K ⁻⁴
- Bm ⁻¹ ~K ⁻¹
- CWm ²
- Dm - K
Correct answer
D. m - K
Step-by-step solution
According to Wien's law the product of wavelength corresponding to maximum intensity of radiation and temperature of body (in Kelvin) is constant ie, _ m T=b= constant where b is Wien's constant and has value 2.89 10⁻³ ~m - K
