Laser light is different from ordinary light. Laser light consists of light waves that all have the same wavelength, or color. The waves are coherent, or in step. A laser is a device that produces a narrow beam of coherent light. The word laser comes from a phrase that describes how it works: light amplification by stimulated emission of radiation. Light amplification means that the light is strengthened. Stimulated emission means that the atoms emit light when exposed to electromagnetic radiation.
The waves get wider and dimmer as they move.
laser light has a constant wavelength whereas regular light is made up of many wavelengths
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
Well.. One thing I can name is laser hair removal. <><><> LASER means Light Amplification by Stimulated Emission of Radiation. Laser light is different from other light. It is tightly focused, and it is "coherent" light-it is all lined up traveling in the same direction. Lasers are used in communication, medicine, measuring distance, as a cutting tool in metal fabrication, measuring speed, and yes, removing hair.
Laser light is made up of coherent and monochromatic light waves. Coherent means that all the light waves are in phase with each other, and monochromatic means that the light consists of a single color or wavelength. This allows laser light to be focused into a tight beam with high intensity and precision.

Laser guns have been a traditional toy for children for decades. They are considered safe because they do not actually fire anything. Instead, a toy laser gun lights up and makes noise. These toys usually resemble space-age sci-fi weapons and not real guns, making it less likely that they would be confused as a dangerous weapon. Some children also play laser tag with guns and vests that fire harmless beams of light.
High resistance wires convert the energy used, into heat. That makes the toaster heat up or the light to turn on.
A laser produces powerful light waves that are coherent, meaning all the waves have the same wavelength and are aligned in phase and direction. This coherence allows lasers to emit a focused, intense beam of light that can be used in various applications like cutting, drilling, and communications.

The color of a beam of light is dependent on its wavelength. A laser will appear as one color because all the light being emitted from it is the same wavelength. This is also why lasers and laser pointers always have such a tight beam. By contrast, flashlights (which have much wider beams, and rely on mirrored interiors to amplify the light) have light at a variety of wavelengths, which is why the light is ultimately "colorless".
