The place in a wave where particles are far apart is called a crest.
When the particles of a wave are far apart, it is in the resting state, or equilibrium position.
When particles of a longitudinal wave are far apart, the amplitude of the wave is at a minimum and the pressure or density of the medium between the particles is at its lowest. This corresponds to a point of rarefaction in the wave.
It is called diffusion when particles spread far apart and fill all the space available.
When particles of a medium are far apart, that part of a wave is called a rarefaction. In a rarefaction, the particles are spread out, resulting in lower pressure and density compared to the surrounding medium.
so far 63 moons have been discovered

63 elements had been discovered so far.
There are (so far) three dimensions of space, and one dimension of time.
There are 26 transuranic elements that have been discovered so far. These elements have atomic numbers greater than uranium (92) and are all synthetic, meaning they do not occur naturally on Earth.

Summer has been around as long as humans can remember, so nobody discovered it. As far as humans are concerned, it has always been there.
the most famous piece of music called "the seasons" (i imagine there are many) was composed by Vivaldi.
No. Far from it. (An enthusiastic 'ditto')
