Waves in water are transverse. This means that the vibrations causing the waves are perpendicular to the direction of energy transfer. As this little boat demonstrates, you can see that the waves are ...

Now, researchers at the U.S. Joint Quantum Initiative (JQI) have designed and tested new chips that can convert one wavelength of light into a trio of hues. Remarkably, says JQI, the chips all work ...

Optical frequency combs are breaking new ground in applications ranging from precision timing to breath analysis. Marie Freebody speaks to Jun Ye from JILA to find out more. Jun Ye is a fellow of JILA ...

A ripple tank can be used to measure and calculate frequency, wavelength and the speed of waves on the surface of the water. A ripple tank is a transparent shallow tray of water with a light shining ...

Can your microwave oven really measure the speed of light? Yes, it can be done. And since many of the suggested experiments also involve chocolate, it will be done. Oh yes, it will be done. First, a ...

Did you know you've been cooking your food with light? Most of us have a microwave oven in our kitchens, and that's exactly what they do. When you press start, a device called a magnetron emits a ...

A series of five new images from NASA’s Chandra X-ray Observatory show the beauty of space as seen in the X-ray wavelength. Data from Chandra has been combined with data from other telescopes ...
