All atomic matter emits electromagnetic waves, since it is all hotter than absolute zero and therefore has some degree of vibration, however slight, which results in electromagnetic waves since atomic matter contains charged particles. However, there are other types of matter. Exchange particles such as photons, gravitons, or pi-mesons, do have matter, but do not emit electromagnetic waves. Dark matter, which seems to constitute a very large part of our universe, does not emit electromagnetic waves.
The sun gives off a large section of the electromagnetic spectrum, so you could say it is many waves all piled together
all electromagnetic waves with the same wavelength
first of all electromagnetic waves are energy waves. and we call electromagnetic waves RADIATION.
maybe? ----- No, you are forgetting about electromagnetic radiation such as a light, radio, x-rays, and so on that also have wave properties. Mechanical waves are able to travel through matter but electromagnetic waves can travel in a vacuum.
In a vacuum, all electromagnetic waves have equal velocity.
All light is transverse waves. All electromagnetic waves, for that matter.

While the sun emits all types of light, from radio waves, to gamma rays the most intense type of light (electromagnetic radiation) is yellow light.

Mechanical waves must use matter as a medium, they displace the matter in space. Examples of mechanical waves are sound waves (must go through gas (air) which is matter), ocean waves (must go through liquid (water) which is matter, and earthquakes (must go through solid (earth) which is matter.Electromagnetic waves do not need matter as a medium and are made of electromagnetic radiation, they cause fluctuations in the magnetic and electric fields that permeate space-time. Examples of electromagnetic waves are radio waves, microwaves, x-rays, and gamma rays (all are part of the electromagnetic spectrum or EMS).
All electromagnetic waves travel at the speed of light in a vacuum.
All electromagnetic waves travel through space. All electromagnetic waves travel through certain types of matter. Some electromagnetic waves (neutrinos and others) pass through all known matter) This is really an extremely complex question, which preys on the nature of waves themselves. I would direct the questioner to read one of the following books: A Brief History of Time (Prof. Stephen Hawking) Coming of Age in the Milky Way (Timothy Ferris)
In a vacuum, all electromagnetic waves/radiation moves at the speed of light (c = 299792458 meters/second). However in matter the speed that electromagnetic waves/radiation moves is reduced by the reciprocal of the index of refraction for that material.
All waves except electromagnetic waves and gravitational waves (predicted by General Relativity, but not yet detected).Some examples are:sound waveswater wavesearthquake wavesetc.
