As the temperature of black body is raised, the wavelength corresponding to maximum intensity:

Explanation

As the temperature of a black body is raised, the wavelength corresponding to the maximum intensity of its emitted radiation decreases. This relationship is described by Wien's displacement law. Specifically, the law states that the product of the temperature and the peak wavelength (λ max) is constant. T . λmax = constant So, as the temperature increases, the wavelength of maximum intensity becomes shorter, and the peak of the emission spectrum shifts toward the shorter-wavelength (blue) end of the electromagnetic spectrum. This phenomenon is observable in various everyday situations, such as observing the color change in a heated metal object (like a stovetop element) from red to blue as its temperature increases.
