Webb14 mars 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 ). WebbExtreme ultraviolet radiation (EUV or XUV) or high-energy ultraviolet radiation is electromagnetic radiation in the part of the electromagnetic spectrum spanning wavelengths shorter that the hydrogen Lyman-alpha line from 121 nm down to the X-Ray band of 10 nm, and therefore (by the Planck–Einstein equation) having photons with … WebbTo plot the radiation pattern of the antenna, specify the frequency at which the data needs to be plotted.
