Ответ:
a. dividing speed by wavelength
Explanation:
The frequency, the wavelength and the speed of a wave are related by the following equation
where v is the speed of the wave, f is its frequency, and
is the wavelength. By re-arranging the formula and solving for f, we find how to calculate the frequency:
Ответ:
All objects are composed of these atoms. ... Charged objects have an imbalance of charge - either more negative electrons than positive protons or vice versa. And neutral objects have a balance of charge - equal numbers of protons and electrons.
