A morning dose of blue light might help older people sleep better in the evening, giving them a boost for their daily ...

"Our tunable-wavelength nitride semiconductor laser oscillates in the 405 nm band, but its structure can be readily adapted to the 460 nm band as well," explains first author Taisei Kusui ...

Remember in the medium where the light is faster (ie bigger speed), the angle is bigger and the wavelength is bigger. A ray of blue light of frequency \(4.8 \times {10^{14}} Hz\) is incident on ...

But do blue-light glasses actually work? And what is blue light anyway? Blue light is one part of the visible light spectrum ...

Panasonic had previously been able to create some of the world’s highest brightness blue lasers using wavelength beam combining. The team hope that, by marrying wavelength beam combining with ...

Researchers have found that blue light exposure in the morning could help regulate sleep times and activity during the day. Experts weigh in on the findings.

Using advanced artificial intelligence (AI) techniques, they trained a neural network to model the dust’s effect on starlight ...

Scientists develop a metasurface that encrypts data using wavelength, wavevector direction, polarization, and diffraction ...
