Visible light and other waves are part of the electromagnetic spectrum. These waves unlike sound waves can travel through vacuums and do so at c (3x10^8 m/s). The spectrum is very broad and includes microwaves, ultraviolet , x-rays, and our own visible light spectrum. These waves are differentiated based on their frequency but all contain photons, mass-less charge-less particles, hence the dual nature of light (light and other waves behave both as particles and waves, confusing i know :P)
basically what this means is that the only difference between visible light, x-rays, and microwaves is the frequency of the photon wave.
The energy we get from the Sun is electromagnetic waves. The sun's energy is considered solar energy and is one of 5 forms of energy.
They are forms of electromagnetic radiations, which all travel at the same speed, speed of light.
The only part of the electromagnetic spectrum that we can see is the small yet significant part of visible light. Visible light is not harmful for humans, but some of the other types of waves are.
Visible light is a small region of the electromagnetic spectrum that is characterized by a specific range of wavelengths and frequencies
Visible light is made of rays. There are rays with wavelengths that are shorter than visible light and other with longer wavelength.
Yes! Light travels through any material that does not completely absorb it. Visible light can only travel through materials that are called either transparent or translucent. Visible light travels through glass all the time. Visible light also travels through your cornea and the gel-like material that is in your eyeball. There are other types of light than visible light, such as ultraviolet (UV). UV is light that has more energy than visible light. This is the type of light that can give you a sunburn. There are even more energetic types of light like X-rays. They go through lots of material that visible light can't -- like skin and organs, but they do not go through bones or teeth very well.
Although visible light has a higher level of energy (shorter wavelength), we are protected from visible light due to the ozone and oxygen particles in the Earth's atmosphere that "trap" the visible light rays damaging energy. Infrared radiation is able to penetrate the ozone because of its wavelength, which allows its rays to reach the earth's surface, be absorbed by the soil and water sources, and be reemitted into the atmosphere causing issues such as global warming, health issues, and other long term effects.

Radiation
broadband blackbody radiation generated by heatnarrow band spectral radiation from excited electrons falling to lower energy atomic orbitals
Visible light falls on the range of the electromangetic spectrum which is the appropriate wavelength to be detected by the eye. The difference between visible light and invisible light is simply its energy (wavelength or frequency)

Electric energy can be converted into many things, all of them are other forms of energy. Electric energy can be converted into heat energy, like in many stoves and ovens. Electric energy can be converted into sound energy, which happens in speakers. Electric energy can be converted into mechanical energy, like with electric motors in fans and other devices. Electric energy can be converted into light energy as with a light bulb. Unfortunately, we do not currently have the technology to turn energy forms into matter as is shown in many sci-fi shows like Star Trek's replicators. Every energy is able to change its type. For example sound energy can be converted into electrical , light, heat and in many other forms.
X-rays, gamma rays, radio waves, and visible light are forms of electromagnetic radiation. Gamma rays are highest in energy compared to other electromagnetic radiations. Radio waves are least in energy in the whole electromagnetic spectrum.

Resistance converts electrical energy into other forms of energy, such as light, heat sound, motion, and magnetic effects.
A lightbulb usually won't use thermal energy, only electrical energy. By conservation of energy, if 10% of the electrical energy is converted into radiant energy, the remainder is wasted - basically as heat.
