Although energy-efficient, quality infrared heaters can be costly upfront, and a few may produce low-level noise. They are best suited for smaller spaces, and using multiple units may be necessary ...

A Japanese research team has "seen the light" and is utilizing infrared wavelengths to generate electricity, an untapped energy source that accounts for nearly half of solar energy striking the Earth.

The Korea Research Institute of Standards and Science has successfully developed a high-quality compound semiconductor ...

When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR sensors are used for applications such as automatically turning on lights when someone ...

Researchers from Stanford University are working on solar panel technology that works at night, which is one of the biggest ...

Visible light covers wavelengths from 400 nanometers to 700 nanometers. Infrared light spans lower-energy, longer wavelengths that humans can’t perceive without specialized equipment.

A presenter-led science video showing how to investigate infrared radiation, with Dr Maggie Aderin-Pocock and Dr Alex Lathbridge. The video investigates emissions of infrared radiation and then ...

Using an optical cavity to confine infrared light waves ... This was attributed to radiative energy transport, in which heat energy is radiated outward as photons from a hot region are absorbed ...

They emit high-energy radiation photons that power the flare. Because the mid-IR spectral range sits between the submillimeter and the near-infrared (NIR), it is keeping secrets locked away about ...
