Ordinary light is emitted from various sources with different phases and wavelengths, leading to random and constantly changing interference patterns. This lack of a fixed phase relationship between light waves prevents ordinary light from being coherent. Coherent light sources, like lasers, have a single wavelength and phase, allowing for stable interference patterns.

What is the main difference between laser and ordinary white light?
The main difference is that laser light is coherent, meaning the light waves are aligned and moving in a single direction, while ordinary white light is non-coherent, with light waves traveling in random directions. Laser light is also monochromatic, meaning it consists of a single color, while white light contains a mixture of different colors.
How lasers and ordinary light different?
Lasers produce coherent and focused light of a single wavelength, while ordinary light sources emit incoherent light of various wavelengths. Lasers also have a much higher intensity and can be tightly focused over long distances compared to ordinary light sources. Additionally, lasers have a very narrow beam divergence, whereas ordinary light sources have a broader dispersion.
What is the difference between a laser and an ordinary light in terms of colors?
A laser produces coherent light that is monochromatic, meaning it emits a single color or wavelength of light. In contrast, ordinary light consists of multiple wavelengths, producing a range of colors. This is why lasers are often used in applications that require precise and specific colors.
What is coherent light?
Coherent light is light in which the electric and magnetic fields are perfectly synchronized and oscillate in phase with each other. This results in a single wavelength and direction, allowing the light waves to constructively interfere and produce a uniform, focused beam. Laser light is an example of coherent light.
A laser produces light that?
is coherent, monochromatic, and concentrated in a narrow beam.
Why are lasers different from other kinds of light?
Because laser light is highly coherent: all one wavelength with all the peaks aligned (all waves completely in phase). Ordinary light is not coherent.
What is the main difference between laser and ordinary white light?
The main difference is that laser light is coherent, meaning the light waves are aligned and moving in a single direction, while ordinary white light is non-coherent, with light waves traveling in random directions. Laser light is also monochromatic, meaning it consists of a single color, while white light contains a mixture of different colors.
How LASER radiation is different from ordinary light?
It is coherent: all the same frequency, all in phase, does not disperse as fast (stays focused).
How lasers and ordinary light different?
Lasers produce coherent and focused light of a single wavelength, while ordinary light sources emit incoherent light of various wavelengths. Lasers also have a much higher intensity and can be tightly focused over long distances compared to ordinary light sources. Additionally, lasers have a very narrow beam divergence, whereas ordinary light sources have a broader dispersion.
Is poly chromatic light can be coherent?
Coherent light (like a laser) is a single frequency. Polychromatic light is, by definiation, multiple frequencies and cannot be coherent.
What is a device producing a coherent light?
The name of the device that produces coherent light is LASER.
What is a device that produce coherent light?
The name of the device that produces coherent light is LASER.

Difference between laser and ordinary light?
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.
Why focusing of laser light is better than ordinary light?
Focusing laser light is more effective than ordinary light because laser light is coherent and monochromatic, allowing it to be tightly focused into a small beam with minimal divergence. This concentrated beam of laser light enables more precise control and greater intensity, making it ideal for applications such as surgery, cutting, and communications.
