frequency

The frequency the light is traveling at also determines how it interacts with matter.

If the grid frequency drops below 59.4 hertz, the clock starts ticking.

They emit soft X-rays, which have frequencies lower than gamma rays, but are still highly energetic forms of light.

A secondary coil is tuned to the same frequency for resonance, and then boosts that voltage, and there you have it.

And if it doesn’t return to the nominal frequency within 9 minutes, the relays trip!

Scientists think squid don’t hear these high-frequency clicks— even as they turn into rapid buzzes and creaks as the whale closes in.

How quickly you reach this threshold depends on several variables, including the frequency, complexity, and novelty of the decisions you have to make.

Tune the size of the hole in the magnet, you get different frequencies of radiation.
