Make a truth teller for light. Turn an old CD into a spectroscope to analyze light—you may be surprised by what you see. Try pointing your CD spectroscope at the fluorescent light in your room, sunlit ...

The world’s largest spectroscopic telescope has just recorded the first observations from its new perch high in the mountains of Chile. Capable of revealing new information about any cosmic object or ...

Researchers have found that 2D materials can self-form microscopic cavities that trap light and electrons, altering their quantum behavior. With a miniaturized terahertz spectroscope, the team ...

IN the first place, then, what does the spectroscope tell us with regard to the radiation from the sun and the stars? And here I ask you to neglect and banish from your minds for a time any idea of ...

Abstract: This paper presents a new methodology to extract spectral information of radiated THz signals to enable a fully integrated broadband THz spectroscope in silicon. A classical down-conversion ...

Playing with light and rainbows is a fantastic project for spring and summer. In this easy STEM Project we are making a Spectroscope which is perfect for the classroom or summer camp. As educators, we ...
