With a neat labelled graph, show the spectral distribution of black body radiation.
Understand the Problem
The question is asking for a graphical representation of the spectral distribution of black body radiation, along with appropriate labels. This involves illustrating how the intensity of radiation emitted by a black body varies with wavelength or frequency at different temperatures.
Answer
The blackbody curve is a graph showing radiation intensity at various wavelengths, peaking at a specific wavelength.
The spectral distribution of black body radiation is typically represented by a black body curve, which is a graph showing the intensity of radiation emitted at different wavelengths. This graph is characterized by a peak intensity at a specific wavelength, which shifts to shorter wavelengths as temperature increases, as described by Wien's Displacement Law.

More Information
The concept was crucial for the development of quantum mechanics. Max Planck first formulated the mathematical description of black body radiation, leading to the quantum theory.
Tips
A common mistake is not recognizing that the peak of the black body spectrum shifts depending on the temperature, which is described by Wien's Displacement Law.
