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.

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.


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 the difference between laser diffraction and ordinary light diffraction?

Laser diffraction involves the use of a laser beam to analyze particle size distribution, providing more accurate and precise results compared to ordinary light diffraction. On the other hand, ordinary light diffraction uses a broader spectrum of light, making it less specific and more prone to errors in measurement. Laser diffraction typically has a higher resolution and can detect smaller particle sizes than ordinary light diffraction.


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.


Is looking at a laser more dangerous than looking at a light bulb of the same intensity?

Yes. There is a huge difference between a 1-watt laser and a 1-watt light bulb. A 1-watt laser will burn a hole in your eye.


Difference between optical and laser mouse?

While both optical in laser mice require a light source in order to detect movement, the difference between the two technologies are optical mice use LEDs as their light source while laser mice use infrared laser that cannot be seen by the human eye. Laser mice are also much more precise than optical mice due to a higher DPI tolerance.


Difference between light emitting diode and laser?

LEDs, known as light emitting diodes, are comprised of two lead semiconductor light sources. Laser transmitters, also known as laser diodes are comprised of an electrically charged semiconductor laser.


What is special about laser light that makes it so useful compared to ordinary light from a light bulb?

Laser is non diverging one and monochromatic. It is coherent and hence highly intense. So laser could be sent even to reach moon's surface and get it back reflected. So distance of astronomical objects could be found.


Why is it so much easier to perform interference experiments with a laser than with an ordinary light source?

A laser emits light that is coherent, meaning the waves are in phase with each other. This coherence enables the laser light to produce well-defined interference patterns when combined with another laser beam or reflected off a surface. In contrast, ordinary light sources emit incoherent light with random phase relationships, making it difficult to observe interference effects.


What is the difference between laser and visible light In terms of wavelength wave frequency and health hazards.?

because that's the way it is....


What is the difference between continuous and pulsed wave laser?

Continuous I assume would mean a constant flow of light from the laser in the form of a wave train. Conversely, a pulse is only a single wave emitted by the laser.


Why laser beam is narrow straightwhere as light from tube light is blury?

A laser beam is a coherent light source that emits a narrow beam of light due to the alignment of its waves. In contrast, light from a tube light is incoherent and emits light in all directions, resulting in a blurry appearance. The difference in coherence and directionality between laser light and tube light accounts for their distinct characteristics.
