Multiple Slit Diffraction Model
The EJS Multiple Slit Diffraction model allows the user to simulate Fraunhofer diffraction through single or multiple slits. The user can modify the number of slits, the slit width, the slit separation and the wavelength of the incident light. The scale of the diffraction pattern can also be changed and a plot of the light intensity can be toggled on and off with a checkbox.
Thick Lens Model
The EJS Thick Lens model allows the user to simulate a lens (mirror) by adjusting the physical properties of a transparent (reflecting) object and observing the object's effect on a beam of light. The user can adjust the concavity of the sides, the index of refraction and its environment, and the height and width of the object as well as the size of the incident light and the horizontal position of the transparent object. Spherical aberration can be observed at large angles. You can examine
Inertial Oscillation Model
The EJS Inertial Oscillation model displays the motion of a particle moving over the surface of an oblate spheroid. The spheroid is flattened to an ellipsoid of revolution because it is rotating, just as the Earth is flattened because it is rotating. The particle is confined to motion along the surface by the spheroid's gravity; the motion parallel to the surface is treated as frictionless. The simulation shows simultaneously the motion with respect to the inertial coordinate system, and the mot

Access to the Internet
Using the Internet depends, in the first instance, on access to the network. The initial emergence of "the Internet" in the early 1990s, from the increasing connectivity of a series of university and government networks alongside private services like America Online, Prodigy, and CompuServe, occurred almost entirely across slow dial-up modem connections over telephone wires. Sufficient for email, Usenet news groups, transferring relatively small files, and later viewing simple web pages, slow tr
