Tools

ray
A single ray of light defined by two points.
Beam
A parallel beam of rays emerges from a line segment, with density controlled by the "Ray density" slider.
Point Source

Point Source

Rays emerge from a single point, with number controlled by the "Ray density" slider.
Mirror

Mirror

Simulate the reflection of light on a mirror.
Mirror (Curved)

Mirror (Curved)

A mirror whose shape is curved. Circular and parabolic curves are available.
Ideal curved mirror

Ideal curved mirror

The idealized "curved" mirror which obeys exactly the mirror equation (1/p + 1/q = 1/f). The focal length (in pixels) can be set directly.
Beam Splitter

Beam Splitter

A mirror that transmits a percentage of incoming light.
Glass

Glass

Simulate the refraction and reflection of light on a surface.
Glass (Other shapes)

Glass (Other shapes)

Glass with any shapes constructed from line segments and circular arcs, including prisms and "spherical" lenses.
Glass (Ideal lens)

Glass (Ideal lens)

An ideal lens that obeys exactly the thin lens equation (1/p + 1/q = 1/f). The focal length (in pixels) can be set directly.
Blocker

Blocker

A line-segment light blocker that absorbes the incident rays.
Ruler

Ruler

A ruler from a point for zero and another point. The scale is in pixels.
Protractor

Protractor

A protractor defined from the center and another point for the zero direction. The scale is in degrees.
Detector

Detector

A tool for measuring the rate of energy flow (P), the rate of perpendicular momentum flow (F⊥), and the rate of parallel momentum flow (F∥) through a line segment. The units are arbitrary.

Views

Show the rays. When the "Ray density" is high, they appear to be continuous.
Low densityHigh density

Extended Rays

Show both the rays and their extension. Orange indicates backward extensions, and gray indicates forward ones.
Extended rays

All Images

Show the position of all images. Yellow points indicate real images, orange indicates virtual images, and gray (none in this picture) indicates virtual objects. Note that some images cannot be detected if "Ray density" is not high enough.
All images

Seen by observer

Simulate the rays and images seen from some position. The blue circle is the observer. Any rays crossing it are considered to be "observed". The observer does not know where the rays actually begin, but may think they begin at some point(s) if they intersect there. The rays are shown in blue, and the point(s) in orange.
