Essentially, sound is a wave of kinetic energy (a mechanical wave) carried through a medium (air in our everyday experience). Drop a pen on the table in front of you. When the pen hits the table, all the kinetic energy you gave it before dropping it has been converted to other forms of energy. Some is absorbed by the table in the form of heat, and some is absorbed into the pen as heat. Some was absorbed by the air on its way down. The pen may have bounced, and all that movement represents the loss of the original energy. When the pen strikes the table, some of the energy is transmitted to the air as an outward spherical pressure front. The molecules of air continue pushing outward and then retracting back because of the trough of lower pressure that is formed behind it. It is very much like waves in a pond; the wave progresses, but the water itself doesn't move very much. When the expanding front of pressure hits something, some of the energy bounces off, and some is absorbed, depending on the materials and design of the object. Whatever is absorbed is in the form of very small quantities of heat. The sound that you hear when you drop the pen is actually some of the kinetic energy you put into the pen, now converted into sound waves.

If you place a piece of black iron out in the sun the light will be absorbed by the black iron. If after an hour you feel the iron it will be hot. Heat is energy and the energy has come form the light, so light is a form of energy.
Light falling on matter raises its temperature. This is evidence that light is a form of energy.
Because it is created by energy and can be harnessed for energy, hence solar panels.

Radiant energy. Light is a form of electromagnetic radiation.
A light bulb IS not a form of energy, it CONVERTS energy. A lightbulb converts electricity into heat and visible light.
Well, this is a very complicated question you're asking here. Let me start. First of all, sound comes in waves and they can be felt with loud music. This movement suggests that they contain energy high enough to vibrate. Light, on the other hand, is a far more complicated question. They produce heat, which makes them energy. Keep reading for details.Scientific research suggests that energy may come in the form of tiny, minuscule strings, invisible even when compared with an atom. Here, since they have no width or height, they are 1-D. This way light may come in energy in the form of strings.
in light photons are there they have energy and energy can be transfered in form of a wave so, it can be a wave
The energy that goes in is electrical energy; the energy that leaves it is visible light, as well as heat.
the fastest form of energy is light
Radiant energy. Light is a form of electromagnetic radiation.
No. Light is a form of energy.
Light is in fact a form of energy along with sound and heat.
A light bulb IS not a form of energy, it CONVERTS energy. A lightbulb converts electricity into heat and visible light.
Light is a form of energy.
Light is one form of energy.
Light is a form of electromagnetic energy.

Light is electric/electromagnetic energy!
Um... yes? Light is a form of energy. Energy has mass.
