Mechanical energy
Yes, a sound wave is a mechanical wave. Sound waves need a medium (like air) to travel through. The energy of the wave, the mechanical energy, is transferred into the medium through which it is propagated.
Sound is energy of mechanical vibration transferred through a medium. Commonly the medium is air, but solids, liquids and gasses all transmit sound. Indeed, sound travels faster through liquid and solids than through gas. Sound does not propagate through a vacuum.
The sun converts hydrogen to light energy. This energy must travel through space, where there are no particles. To go through space, the energy is transferred by electromagnetic waves. When these waves hit the Earth's surface, they are absorbed by the typeof material at the top (rock, soil, water). As the waves are absorbes, they release their energy into the material's particles. This causes the particles to vibrate faster, causeing heat.

Light is an example of electromagnetic radiation. EM radiation unlike other waves of energy doesn't need a medium to travel through hence why light energy can travel from the sun to the earth through the vacuum of space.
heat or light radiation can travel through a 100% vacuum
Disturbances that transfer energy, or waves. Mechanical waves must have a medium to travel.
Electromagnetic Energy does not require matter to be transferred...that is why it can travel through the vacuum of space.
That is one way thermal energy can be transferred.
This question has two answers. The Sun, itself, is a big boiling pot of gases that generates mass amounts of energy through the process of nuclear fusion. That energy transferred to the planets around it through radiation, which are waves of charged particles that are able to travel long distances. Therefore, the Sun has two energy forms, though it uses only nuclear energy for itself.
When waves travel from one point to another energy is transferred through the medium. Waves are periodic vibrations or oscillations in a medium that propagate through the medium carrying energy in the form of the movement. Exceptions to this are light and gravity waves, which do not require a medium for propagation.

Heat and light energy travel through space and matter
Sound is a mechanical wave that can best be described as a 'vibrational' form of energy. It propagates throughout a space by vibrational motions of molecules. In other words, it does not technically travel through oxygen molecules but the sound energy makes the molecules vibrate. As the molecules vibrate, the energy is passed on to other molecules by collision and therefore the energy is transferred on and on. Without a medium to travel through, sound energy cannot propagate or travel. In other words, if a bomb goes off in the middle of space or a vacuum, you will not be able to hear the explosion no matter how close you are to the explosion.
Light actually travels in waves.This is known to be true because there are only 3 ways that energy can be transferred. As you probably already know, light does not need a medium to travel through because it travels through space. Electromagnetic waves are the only form of energy transfer that do not require a medium to travel through.
E.M. waves require no medium. Sound waves require a medium.
