Problem

According to the displacement law for a perfect blackbody, the product λmaxT\lambda_{\text{max}}T is equal to a) 2.098×10−3 m K2.098\times10^{-3}\,\text{m\,K} b) 2.898×10−3 m K2.898\times10^{-3}\,\text{m\,K} c) 5.770×10−3 m K5.770\times10^{-3}\,\text{m\,K} d) 2.898×10−2 m K2.898\times10^{-2}\,\text{m\,K}
Intuitive explanation

Wien's displacement law connects the wavelength of peak emission to temperature—it tells you that hotter objects radiate their peak intensity at shorter wavelengths. The key insight is that this product λmaxT\lambda_{\text{max}}T is a universal constant, independent of what the object is made of. You're really just identifying which fundamental constant governs this relationship and understanding why it emerges from the physics of thermal radiation.
