Is a light of a flash light a ray of light?

Answer 1

Light is made up of light waves, which are different than normal waves because they do not need a medium, or a material to travel though. (Some examples of mediums are water, air, wood, metal...). Light waves come in different sizes, or wavelengths. Flashlights usually use incandescent light bulbs to produce light. Incandescent light bulbs produce light by heating a tungsten filament until it glows and gives off heat under the form of light waves.

Answer 2

Yes, the light emitted from a flashlight can be considered as a ray of light. It travels in a straight line from the source in all directions until it hits an object or surface and reflects off or is absorbed.
