How do you determine the amplitude of a transverse wave

The amplitude of a transverse wave is the difference between the height of  crest which is the maximum point and the resting position the minimum point of one curve of a wave.

Please look at the attachment to see the figure to make the answer more clear.

Transverse waves are those that moves in the direction along x-axis

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
