What is light?
Light is a form of energy which gives a sensation of sight to eyes. It enables the eyes to see objects by the light the objects reflect or shadow.
Light is a part of the electromagnetic spectrum. Some restrict "light" to what humans can detect with our eyes but many scientists simply use the word light to mean any and all forms of electromagnetic radiation. To refer to light we can see, they often use the adjective "visible".
Electromagnetic radiation is particle-waves. It possesses properties of both particles and waves. It has both a vibrating electric field and a magnetic field, each at right angles to the other and at right angles to its direction of travel. It is always travelling at a speed of roughly 2.998 x 10 8 metres/sec. Experiments with the photoelectric effect shows energy is transferred between atoms in discreet packets of energy suggesting a particle nature. In any case, "waves" and "particles" are only abstractions we use to visualise what we can't imagine because it is outside of our normal frame of reference.

homogeneous light is usually considered to be light of a single wavelength. for example, red light or blue light would be considered a homogenous light because it consists of one single wavelength. the opposite of homogeneous light would be light consisting of multiple wavelengths, for example green light (has yellow and blue light) or white light (has light of all visible wavelengths).
