The intensity of light from most light sources is inversely proportional to the square of the distance from the source. So the intensity two meters from an incandescent lamp is one quarter of the intensity at one meter, and at three meters from the lamp the intensity is one ninth of the intensity at one meter. Laser light ideally has the same intensity at any distance.
Yes. A Christmas light string composed of LED lamps can be connected on an incandescent light string. The outlet at the end of a Christmas light string has (or is supposed to have) the source voltage.

Laser light is different from light in a light bulb because it is focused, coherent, and monochromatic. This means that laser light is concentrated, all the waves are in step with each other, and the light consists of a single color or wavelength. Conversely, light from a light bulb is diffuse, incoherent, and contains multiple wavelengths/colors.
An ordinary frosted incandescent bulb is a luminous source because it produces light through its own incandescent filament. It does not rely on external light sources to produce light.
No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.
Incandescent light bulbs are used, in addition to LEDs. LEDs or laser emitted diodes, produce the different colours with different electricity molecules mixing with the oxygen in the air

The costs of manufacturing costs of fluorescent and incandescent light bulbs are about the same aside from the slight different materials.
laser light has a constant wavelength whereas regular light is made up of many wavelengths

Laser light is different from visible light in several ways. Laser light is monochromatic, meaning it consists of a single color or wavelength, while visible light contains a range of colors. Laser light is also coherent, meaning its waves are in sync and travel in a straight line, unlike visible light which scatters in different directions. Additionally, laser light is intense and focused, making it useful for various applications such as cutting, welding, and medical procedures.

An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a wire filament heated to a high temperature by an electric current passing through it, until it glows.
No, a burner is not considered incandescent. Incandescent refers to light produced by a hot object, like an incandescent light bulb, not a heat source like a burner.
Laser lights are spectrally pure, i.e. one wavelength, and they are coherent, i.e. all phota in phase. As a result, the beam of a laser light tends to stay as beam, and not diverge due to scattering.
Incandescent light bulbs work by passing electricity through a filament, which heats up and produces light. They are different from other types of light bulbs because they rely on this heating process to produce light, whereas other types, like LED or fluorescent bulbs, use different mechanisms to generate light.
