photons
A monochromatic source is a source of light of a discrete wavelength. White light is a mixture photons with wavlengths from 390 to 750 nm (what the human eye can detect). The monochrmatic light will have a specific wavelength. For example all photons have wavelength 200 nm.
The photons spread over a larger area
Not many things have no mass however Photons (Light Particles) have no mass and therefore they travel at the speed of light.

Outward from the source.
No. All photons travel at the speed of light.
decreases in proportion to distance from the object squared. A good example in the link below.

You don't. The only objects that can travel at the speed of light are those that ONLY travel at that speed, like photons or gravitons.

No light is composed of massless particles called "photons", the reason some lights such as torches, seem to weaken the further they get from the torch, is because the light from a torch is not as focused as the light from a laser beam, the photons that make up the light, simply spread out over greater distances. Photons themselves do not weaken, they will travel until they reach an object they cannot pass through.
Photons created by burning elements and gas are reflected off the inner mirror and projected outward. Flashlight by light source, battery, circuit, a hood and a reflective cup, circuit storehouse, switch, etc, the basic principle is the current from the battery, and then to the circuit, after adjusting circuit voltage and current, and then output to the light source for lighting.
