The inside of giant planets can reach pressures more than one million times the Earth's atmosphere. As a result of that intense pressure, materials can adopt unexpected structures and properties.

A virtual laboratory under development at the University of North Carolina at Greensboro aims to let students experiment with physics concepts without physically being in a lab. Computer simulations ...

When a laser beam is incident on a narrow opaque object such as a fine wire or a strand of hair, the resulting diffraction pattern is similar to the diffraction pattern of a slit of the same width as ...

(Left) 3-D printed parts provide the stands for the aluminum globes in PPPL's Planeterrella, a device that simulates Northern Lights. (Right) This 3-D printed part replaced the meter's original handle ...

Mount the laser and diffraction plate on opposite ends of the rail, making sure the laser is pointed away from people. Plug in the laser and aim it at the desired pattern, maximizing the intensity of ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

Laboratory astrophysics is the study of astrophysical phenomena in the laboratory (Earth- or space-based). This might include various aspects of astrochemistry (chemical reactions under extreme ...
