The reason is that contour plot lines where your field has the same value, keeping the rest of the plot empty. On the contrary, contourf or imshow fill the empty space with the colormap you …

Aug 13, 2023 · The goal here is to model the pattern of light you get when a laser passes through a double slit. There’s a lot of stuff to do for this, so let’s get started.

The software is written in Python using NumPy for the calculations, TkInter for the interface, and the Python Imaging Library to produce the 2D plots. Those libraries are available for Windows, …

The file diffraction.py contains the three functions for single, double and diffraction grating normalized intensities. The file single_slit_diffraction.py contains code that uses the above …

Interference examples. When two or more waves overlap each other in space a more or less complicated pattern of fringes can be observed on a screen placed in the overlap area.

Jan 15, 2025 · In this part of the lab, you will use the function you created above to plot graphs of two wave functions (y vs. t), and the result of how they interfere. In order to make a plot in …

# Function to calculate the intensity at a point on the screen

May 23, 2017 · Similar to the interference pattern here, I would like to create an animation of this interference pattern changing as fringe transitions occur - ie as fringes emerge from the centre …

Feb 12, 2024 · import numpy as np import matplotlib.pyplot as plt # Parameters wavelength = 5.0 # Wavelength of the waves k = 2 * np.pi / wavelength # Wave number …
