Any light source.
No, microwaves aren't visible to humans. Microwaves are electromagnetic energy, and the only electromagnetic energy humans can see is that of visible light.
The radiant energy of electromagnetic waves in the visible portion of the electromagnetic spectrum.
The radiant energy of electromagnetic waves in the visible portion of the electromagnetic spectrum.
Visible or optical electromagnetic waves.
A piece of wood is not considered electromagnetic energy. Electromagnetic energy refers to the energy carried by electromagnetic waves, such as light, radio waves, and X-rays. Wood does not emit or interact with electromagnetic waves in the same way that energy does.

Visible or optical electromagnetic waves.
Visible light is a type of electromagnetic waves.
electromagnetic waves are longitudinal (like a slinky).
A piece of wood is not considered electromagnetic energy. Electromagnetic energy refers to the energy carried by electromagnetic waves, such as light, radio waves, and X-rays. Wood does not emit or interact with electromagnetic waves in the same way that energy does.
Any electromagnetic energy whose wavelength is between roughly 390 and 750 nanometers is visible, if some of it happens to enter your eye. By traditional usage as well as international agreement, this type of electromagnetic energy is widely referred to as "visible light".
Energy, from the sun, reaches us in the form of electromagnetic radiation.
This is variously known as light energy, radiant energy, and electromagnetic radiation.
Yes, "visible" light.
