The electromagnetic spectrum is a continuum so that the boundaries between its parts are arbitrary.
From waves with the largest wavelengths (lowest frequencies and energies), they are:
The arbitrariness is seen in the boundary between visible and ultraviolet, for example. Many insects can see near ultraviolet.
The electromagnetic spectrum does not contain sound waves. It includes a range of electromagnetic waves, from radio waves to gamma rays, but does not include mechanical waves like sound.
Energy carried by electromagnetic waves is called electromagnetic energy. These waves contain a mix of both electrical and magnetic fields, moving at the speed of light. Different types of electromagnetic waves include visible light, radio waves, microwaves, and X-rays.
Light waves contain electromagnetic energy. This energy is in the form of photons, which are packets of electromagnetic radiation that carry energy and momentum.
The common name for electromagnetic waves is just that: "electromagnetic waves". There is no other commonly used term. Specific parts of the spectrum have common names, for example light (or visible light), radio waves, x-rays, etc. - but none of this means exactly the same as "electromagnetic waves". Visible light, for instance, is just one type (or frequency range) of electromagnetic waves.

Energy carried by electromagnetic waves is called electromagnetic energy. These waves contain a mix of both electrical and magnetic fields, moving at the speed of light. Different types of electromagnetic waves include visible light, radio waves, microwaves, and X-rays.
Electromagnetic waves were predicted, by calculations, by James Clerk Maxwell. Later, different parts of the electromagnetic spectrum were either discovered or confirmed to be electromagnetic waves by various scientists.
Light waves contain electromagnetic energy. This energy is in the form of photons, which are packets of electromagnetic radiation that carry energy and momentum.
Radio waves ARE electromagnetic waves.
Electromagnetic waves are transferred by electromagnetic radiation.
