frequencies

From further back, the difference in frequencies is small and the effect less obvious.

For example, while investigating how the chemical structure of the carotenoid pigments affects the determination of color, Kuhn showed how the backbone sequence of single and double-bound carbon atoms give the polyenes their light absorbing properties and how slight variations create important differences in frequencies of light that could be absorbed - i.e. the variant colors we observe.

That image of a bunch of college students pouring water in and out of Coke bottles until they whistle at the proper frequencies is irresistible — the low-tech, hands-on, trial-and-error origin of the digital sound world we live in now. posted by Matthew @ 10: 30 AM

First, it does not distinguish random changes in frequencies in finite populations from changes that are a consequence of different biological properties.

To cite a rather grim example, certain frequencies can kill.

The comparison between two light frequencies is made with a beat technique that shows the difference in frequency low enough to be measured.
