Regardless of the kind, every wave has an amplitude. Amplitude is the maximum displacement of points on a wave, which you can think of as the degree or intensity of change. This maximum displacement is measured from the equilibrium position.The picture below shows a diagram of a sine wave.mplitude is an important parameter of waves and is the maximum displacement of points on a wave. Stated another way, amplitude is the vertical distance between a peak or a valley and the equilibrium point. Frequency is the number of wave cycles passing a point per unit time.
Darkfield Digital Image Gallery Dogfish Shark Placoid Scales Dogfish sharks are small sharks belonging to one of three families: the dogfish shark family, Squalidae; the requiem shark family, Carcharhinidae; and the cat shark family, Scyliorhinidae.he green dogfish, along with several other members of the dogfish shark family, is luminescent. Scales are small plates that form part of the skin of certain animals. They provide protection from the environment and from predators.

Broad leaved plants are recommended and are rarel... Zebra Pleco (Hypancistrus zebra). The Zebra Pleco is an opportunistic feeder in the wild though they scavenge on fallen fruits and decaying vegetable matter (as is expected o... Plecostomus are large algae eating fish from South and Central America. They are known in the aquarium hobby as Sucker Fish, Suckers, or even just Algae Eaters. There are many different types of Plecostomus and many of them require very different water parameters, food and cover.
