A well tested concept that explains a wide range of observations is called a Scientific theory
-- The amplitude of Wave-1 is greater than the amplitude of Wave-2 ...
possibly 3 or 4 times as great.
-- The wavelength of Wave-1 is longer than the wavelength of Wave-2 ...
maybe almost twice as long.
-- The frequency of Wave-2 is greater than the frequency of Wave-1 ...
maybe almost twice as frequent.
The nucleus is the center of the atom made up of protons and neutrons with an overall positive charge. this is where the majority of the atom's mass is.
the electron cloud is the energy levels filled with electrons orbiting the nucleus, there is hardly any mass and it has an overall negative charge equal to that of the nucleus it is orbiting if it is part of a neutral atom.
