Demo

The propegation of waves from a point source are animated according to Huygens' principle.

Hygncirc

Moderate

An incoming ray, at any angle, is refracted through a user-defined surface.

Simplen

Intro

An incoming ray srtikes a flat surface, and is then refracted through the surface.

Refract

Moderate

An addition to the program Refract; a reflected ray is also drawn.

Refrref2

Moderate

Explores the relationships between the electric and magnetic modes at a glass-air interface

Frefl1

Moderate

By use of the law of reflection (angle of incidence equals angle of reflection), parallel rays are shown striking a spherical mirror. (Other applications)

Sphmir

Moderate

By use of the law of reflection, parallel rays are shown striking a parabolic mirror.
(Other applications)

Parmir

Complex

Exact ray tracing of parallel rays from infinity is done on a lens to show refraction at both surfaces.

Lens7

Intro

Plots the intererence pattern for two point sources / Young's Double Slit Experiment

Basinfr

Moderate

Plots the interference pattern for various numbers of point sources; shows how changes in amplitude & spacing affect the interference pattern

Cpxinfr

Moderate

Plots the interference pattern for different numbers of point sources.

Difintr

Moderate

Shows partial coheence through a double slit by adding incoherently interference patterns from parts on an extended source.

Partcoh1

Moderate

Shows the intensity of a zone plate depending on the poition of the source (y and z). (Related Article)

Arago2

Moderate

Plots the intensity as a function of distance away from the center of the zone plate.

Zoneamp

Demo

Draws a zone plate.
