Electrons in an excited state are more likely to enter into chemical reactions true or false

The answer to your question is true.

Hi (best friend)! Here is what you missed!

Five wave parameters are defined and measured: the time, the frequency, the amplitude, the wavelength, and the speed. The wave length is the time it takes to pass a full phase. The frequency is just the opposite; it's the number of wave cycles that have been completed in a second.

Lets give a wave of water as an example. Its wavelength is the distance from crest to crest or from trough to trough. The wavelength can also be thought of as the distance a wave has traveled after one complete cycle—or one period. The time for one complete up-and-down motion is the simple water wave’s period T. In the figure, the wave itself moves to the right with a wave velocity vw. Its amplitude X is the distance between the resting position and the maximum displacement—either the crest or the trough—of the wave.
