Multiple Reflections

This is the famous "Mirrored Room" at the Knox-Albright Art Gallery. If you look closely, you can see:
-- a table and chair, which are covered with mirrors, like the walls
-- the hood around the camera that was used to take the picture.
To learn more about multiple reflections, visit this Physics Classroom page, and also see the simulation Multiple Reflections from Two Plane Mirrors.

The Photoelectric Effect

Security note:
Once you have clicked on the "simulation" link below, be sure to read the Java Security Advisory before running the simulation: To do that, click the "Read now" button on the yellow band near the top of the PhET page.

Check out the PhET simulation The Photoelectric Effect from the University of Colorado to learn about the photon, and the photoelectric effect in particular. For more, visit The Photoelectric Effect, from Physics 2000.

Roundup At the Optical Corral

Although this image looks like electron waves in an "atom corral" (scroll down to see the image), it's actually a theoretical optical corral--a prediction--with the waves representing quantum states of light. To learn more, see the American Physical Society's Physical Review Focus Roundup At the Optical Corral.
