Total tissue water responded as predicted by van't Hoff's osmotic relation to H2O?diluted seawater but was not clearly affected by the admixture of seawater with isosmotic MgSO4, suggesting that this solution may act as an isotonic medium.
Disturbance of symmetry results in a net electron current; a pulse of electromagnetic radiation is emitted which is strongest in directions per- pendicular to the net current.
Another example of a pulse is a tsunami, a tidal wave of energy that travels. many miles over an ocean. But many waves are generated by a cyclic vibration of some. given frequency. This type of wave is referred to as a sine wave. Sine waves are used. to describe many features of radiant energy.
