Yes it is. That is why you get a scrachy and unclear sound.

What is a source of digital light?
Light is not naturally digital - perhaps you mean solid state? Digital light as in a fibre-optic cable is just laser light modulated.
Does any radio frequency used for laser communication?
no. LASER uses light frequencies.
A helium neon laser emits light of wavelength 633 nm Light from an argon laser has a wavelength of 515 nm Which laser emits the higher frequency light?
according to the wave theory of light,we have the relation that wavelength is inversely proportional to the frequency,therefore the electromagnetic wave with the lower wavelength will have higher frequency..
What is the Frequency of a Laser?
An electron beam has no inherent frequency. It can be modulated by a signal that has a frequency. The individual electrons in the beam will have a quantum frequency proportional to their energy, However these are two different phenomena and it is not clear from your question which you are asking about.
How can you tell the difference between a laser and a beam of white light?
A beam of white light is white. A laser is not; it's monochromatic (one specific frequency of light, therefore colored and not white).
Does the color of the laser affect the velocity of the light wave projected by the laser?
No, velocity and color are independent. Color is determined by frequency, and speed is determined by what material the light is traveling through.
Can a laser pointer make a rainbow with a prism?
A laser beam consists of a single frequency of light, therefore it cannot form a spectrum or rainbow.
What has the author Robert Edward Rowlands written?
Robert Edward Rowlands has written: 'A sequentially modulated ruby laser system for transmitted and scattered light dynamic photoelasticity'
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.
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.
How is a light beam different to a laser beam?
Compared to regular light, a laser beam: * Is monochromatic. All the photons have the same frequency, and thus the same energy. * All the photons have the same phase.
Does the frequency or wavelength of a laser affect the velocity of the light wave projected by the laser?
No. The frequency of the entire electromagnetic spectrum varies continuously from low to high frequency. The speed of light remains a constant 186,000 miles per second. That is 300,000 km/sec.
