University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in ...

Just think: You can measure this extremely important quantum constant using very simple materials—essentially just LEDs, a voltmeter, and a diffraction grating.

Obviously the wavelength of a laser can’t be measured with a scale as large as that of a carpenter’s tape measure. At least not directly and that’s where a Compact Disc comes in. … ...

Physicists have developed a fast and sensitive mechanical tool to measure light. The graphene nanomechanical bolometer is the fastest and most sensitive in its class. It is poised to detect nearly ...

When radio waves travel as fast radio bursts toward Earth, their light can be measured in different wavelengths that spread out. How much the light spreads out is dependent on how much matter is in ...

Performing high-resolution, high-sensitivity measurements of light and matter at the quantum limit requires extraordinary tools. Due to the difficulties of manipulating atoms with the necessary ...

There’s a little more to it, of course; the method is based on measuring the voltage at which LEDs of various wavelengths start shining, so a simple circuit was built to select an LED from the ...

value output is carried out via a USB connection, which also serves as a power supply. In addition, the wavelength information is available as voltages of up to 4.096V at the analogue output. The ...
