Researchers have cracked a fundamental optical challenge: how to control both angle and wavelength of light independently—a ...

(Example: Students share measured wavelengths and generate one graph from all of the collected data to understand the ranges of wavelengths associated with each color of visible light.) Engaging in ...

Light can have wavelengths well outside what our eyes can see, too. Scientist William Herschel figured this out in the 19th century , when he found he could still feel heat from sunlight even when ...

Scientists have combined two light wavelengths to deactivate a bacterium that is invulnerable to some of the world’s most widely used antibiotics, giving hope that the regime could be adapted as ...
