Using the controls, the amplitudes and wavelengths of the waves as well as their phase difference (the phase of Wave 2 relative to Wave 1) can be adjusted. The waves as they move forward are shown between two planes the electric field vectors are displayed at the planes. In EMANIM, you can set up two waves ( Wave 1 and Wave 2) with selectable polarization (horizontal, vertical, left circular or right circular) and you can show their superposition ( Wave 1 + Wave 2). For clarity, only the electric component is shown at all times (the magnetic component is always perpendicular to the electric component and its magnitude oscillates in the same phase as that of the electric component). The GIF file can be downloaded from the output area and viewed in the browser.EMANIM animates electromagnetic waves in vacuum and in matter. As you change various options, you can see the summary of the resulting GIF parameters in the options. The option that changes the repetitions is called the loop count option. The information about repetitions is written to the header part of the GIF file and when the GIF is downloaded it will play the number of times you selected. The animation can be repeated just one time, multiple times, or an infinite number of times. Usually, all GIF frames have the same delay but if necessary, you can enter a comma-separated list of individual frame delays for each frame. When the GIF is created, each frame is assigned a delay value, which is the number of milliseconds that the frame is displayed on the screen. The colorful output GIF can have as many frames as you want and the number of frames can be set in the options. The dimensions of the GIF file are set by changing the width and height of the first frame in the options. The "Draw Random Colors" mode shuffles the colors in the options and displays them in a random order in the animation. For example, if there are 7 frames and 3 colors: c1, c2, and c3, then the frames will be colored as follows: c1, c2, c3, c1, c2, c3, c1. If there are more frames than colors, then the program repeatedly cycles through the color list and re-draws the colors in order multiple times. The "Draw Colors in Order" mode creates a GIF with one color per frame that go in the order that they are specified in the options. This way when the GIF reaches the last frame that contains the last gradient color, it will start from the first color, which is the same as the last color, so there will be no discontinuity in the gradient animation. To achieve an infinite gradient loop, make sure the first color and the last color are the same. When the frames are animated, you get a smooth frame-by-frame gradient. The "Draw a Color Gradient" option takes several colors that are entered in the multi-line color option and generates a color spectrum from them that's then spread across all the GIF frames. The "Draw a Solid Color" option fills the background of all GIF frames with one solid color that you selected from the color palette or entered by its name. ![]() It allows you to make animated and static GIFs that are filled with colors of your choice. This is a browser-based program for generating colorful GIFs. ![]()
