For longitudinal waves, the compressions and rarefactions are analogous to the crests and troughs of transverse waves. All electromagnetic waves are transverse, Here the upper curve is called crest, And the lower curve is called trough. The definition of a trough is a long and narrow container.

In a medicine that is administered periodically, the trough level should be measured just before the administration of the next dose in order to avoid overdosing. If you live on a farm, you already know that a trough is what animals eat out of. Trough: The trough is the lowest point in a wave. low point is called the trough. Time for 1 oscillation, t = 20/50 = 0.4 s. Frequency of 1 oscillation, f = 1/0.4 = 2.5 Hz.

(A) A wave consists of alternation crests and troughs. Troughs of medication concentration occur after the drug has been broken down and metabolized by the body. The number of reactant molecules present in the rate-limiting transition state is equal to the reaction order. Which of the following are the expected observations when a small piece of barium is added to a trough of water containing a few drops of methyl orange? Varying the wavelength of light changes its color; varying the wavelength of sound changes its pitch. The trough will intensify (deepen further southward) if cold air continues to move southward at low levels in the troposphere. chemistry. Figure 1. The lowest part is called the trough.
