Light bulbs aim to emulate the light emitted by the Sun, which radiates as a black body at 6000 degrees C. The light is emitted over the entire visible spectrum.
Some bulbs produce monochromatic light, sodium street lights for example.
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.
Monochromatic light is light of one wavelength. E.g. A red laser has one single wavelength and is therefore categorised as 'monochromatic light'. A standard light bulb emits light of many different wavelengths across the visible spectrum and therefore is not 'monochromatic light'.
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.
The wavelength of light emitted by a 25 watt incandescent light bulb corresponds to the visible spectrum, ranging from about 400 to 700 nanometers. It primarily emits infrared radiation, with some visible light. The specific wavelength depends on the bulb's temperature and materials used.
The light bulb gives light be heating the filament. Roughly speaking, it is emitting black body radiation. Plank's Law gives you the formula. See here: http://en.wikipedia.org/wiki/Black_body http://en.wikipedia.org/wiki/Planck's_law

An example of emitted light is the light produced by a light bulb when it is turned on. The light bulb emits visible light by converting electrical energy into light energy.
The level of radiation emitted by a light bulb is very low and considered safe for everyday use.
Monochromatic light is light of one wavelength. E.g. A red laser has one single wavelength and is therefore categorised as 'monochromatic light'. A standard light bulb emits light of many different wavelengths across the visible spectrum and therefore is not 'monochromatic light'.
The glass covering a light bulb is called a bulb or bulb glass, which protects the filament and controls the direction of light emitted.
If iron is used, there will be no light emitted from the light bulb as iron is opaque.
Yes, lasers emit coherent monochromatic light due to the process which light is created. It is created by exciting molecules continuously to one energy level and emitting the energy back to a sort of chain effect as the emitted light is partially used to excite more molecules, therefore due to the specific energy level changes in the excited medium, the light emitted is of one specific wavelength.
A light beam is a broad spectrum of electromagnetic radiation emitted by a source like the sun or a light bulb, while a laser beam is a focused, coherent beam of light produced by stimulated emission of radiation. Laser beams are more intense, monochromatic, and directional compared to regular light beams.
An incandescent bulb emits a continuous spectrum of light, which includes all colors of the visible spectrum.
The laser causes the stimulated emission of radiation. The light emitted is monochromatic and coherent,that is plane polarised. I imagine that spontaneous emission occurs in a Light emitting diode ,monochromatic but not polarised. Hope this is of help
When a particle passes through a light bulb, it interacts with the atoms in the filament of the bulb. This interaction can cause the particle to lose energy, which results in the emission of light. The emitted light is what we perceive as the light produced by the light bulb.
Monochromatic light is light composed of a single wavelength. One example of monochromatic light is the laser, which emits light of a very specific color or wavelength, making it highly monochromatic.
