WebFeb 19, 2024 · Planck’s law of radiation describes the radiation emitted by black bodies. However, there are different forms of representation, which will be discussed in more detail in the following.

WebMar 14, 2014 · Here's a basic plot. To plot using plt.plot (x, y, fmt) you need two arrays x and y of the same size, where x is the x coordinate of each point to plot and y is the y coordinate, and fmt is a string describing how to plot the numbers. So all you need to do is create an evenly spaced array of wavelengths (an np.array which I named wavelengths ).
