In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

Researchers have reached near-unity response ranging from ultraviolet to infrared, outlines a new report. Researchers at Aalto University reach near-unity response ranging from ultraviolet to infrared ...

Free-electron lasers are extremely versatile research tools because their intense, super short light flashes permit a closer look at new materials and even biological molecules; thus, allowing effects ...

Fiber-optic networks zip billions of bits of information across the world every day, using light with a wavelength of 1,550 nanometers, which is well suited for snaking through kilometers of glassy ...
