Photons travel outward from a light bulb in all directions.
When a light bulb is switched on, electricity flows through the filament, causing it to heat up and emit light. The light becomes visible as it emits photons that travel at the speed of light, reaching our eyes almost instantly. This gives the immediate perception of light.
Light waves originate from a light source, such as the sun, a light bulb, or a laser. When an object absorbs energy, it can emit photons, which are the elementary particles of light that travel as electromagnetic waves.
A light bulb provides light through emission of photons due to electrical energy, and is not directly related to reflection or refraction. However, when light emitted by the bulb interacts with a mirror, it undergoes reflection, while when it passes through a lens or prism, it undergoes refraction.
Both the Sun and a light bulb produce light through the process of electromagnetic radiation. This involves the emission of photons, which are particles of light that carry energy. In both cases, this energy is converted into visible light that we are able to see.
Light cannot travel faster than the speed of light, so a bulb traveling at the speed of light is not possible in the laws of physics as we know them. If it were somehow possible, the bulb may emit light, but we cannot definitively predict what would happen under such extreme conditions.

A light bulb transfers electrical energy into light and heat energy when it is turned on. The electrical energy is converted into photons, which emit light when passing through the bulb's filament.

Light has heat and light energy. Example is bulb.
In 1960, Theodore Maiman invented the laser while working at Hughes Research Laboratory. The laser emitted photons that struck other photons and generated more photons. The set up allowed for a systematic emission of photons, and after gaining ample intensity they formed a consistent beam of light.
In a straight line. At the speed of light.
A light bulb is an example of radiation because it emits electromagnetic radiation, in the form of visible light, when an electric current passes through it. This radiation is generated by the excitation of electrons in the bulb's filament, causing them to release photons and produce light.
When electrons flow through the filament of a light bulb, they collide with the atoms of the filament material, causing them to heat up and emit light in the form of photons. This process is known as incandescence and is what generates the light produced by the bulb.
Light, of course, since that's what the light bulb is designed to produce. There is also waste energy, as heat, and (to a small extent) as sound.
When electrons move through the filament of a light bulb, they collide with atoms in the filament material, transferring energy. This energy causes the atoms to vibrate and release photons, which are the particles of light that we see. This process produces heat and light, which creates the illumination from the light bulb.
