Energy is a property of objects. This is taught in science.
The electron's definite energy is based on it's location around the nucleus
Niels Bohr
Planck
The properties of a solid include having a definite shape and definite volume. The particles of a solid are close together, vibrate in place, and have low kinetic energy.
A solid has atoms which are more tightly packed and has less energy than gases or liquids so they can't move that much. Liquids and gases move faster because they have more energy which comes from heat.
A traveling wave is a type of wave in which energy is transmitted in a definite direction and with a definite speed.
Quantisation of electric Field consists of discrete energy parcels, photons. Photons are massless particles of definite energy, definite momentum, and definite spin.

A solid has a definite shape because of kinetic energy. Its molecules are very strong, and because of kinetic energy, they are tightly packed together creating mass and volume that makes up a definite shape.

The properties of a solid include having a definite shape and definite volume. The particles of a solid are close together, vibrate in place, and have low kinetic energy.
A transverse wave would cause the displacement to be perpendicular to the direction. They will also be moving at a constant speed.
Quantum
A solid has atoms which are more tightly packed and has less energy than gases or liquids so they can't move that much. Liquids and gases move faster because they have more energy which comes from heat.
The enrgy is always lost or gained in only the definite amount that is called as discrete or packet energy.
