Both UVA and UVB rays can damage your skin, just in different ways. One causes premature aging, the other is more prone to causing sunburn, DNA damage, and skin cancer.

Leveraging the strong correlation of link gains in multi-wavelength Petahertz communication, this work proposes an adaptive transmission framework based on a low-dimensional feature vector.

Moonlight's colour varies. It depends on Earth's atmosphere. The Moon reflects sunlight. Atmospheric particles scatter light.

Is black a colour? Black isn’t in the rainbow, but where does it fit in the colour spectrum? What makes something appear ...

We propose and experimentally demonstrate an all-optical filter with tunable bandwidth and wavelength based on cascaded opto-mechanical microring resonators (MRRs). As the transmission of each MRR ...

Sunlight is not just light. It’s a spectrum. If you’ve ever seen a rainbow or passed sunlight through a prism, you’ve seen ...

What color is moonlight typically, and what other colors can moonlight look like from our perspective on Earth?
