So-called Rayleigh–Bloch waves can release an enormous amount of energy that can damage technical systems under certain circumstances. They only exist below a precisely defined cut-off frequency ...

It might seem like a simple question. But the science behind a blue sky isn't that easy. For starters, it involves something ...

Yet the age-old question remains unanswered: Are we alone? So-called Rayleigh–Bloch waves can release an enormous amount of energy that can damage technical systems under certain circumstances.

Since the blue waves become separated from the rest of ... and the sun emits more blue than violet energy. We also see the Rayleigh effect at play in: -Sunsets where the sky is red.
