That's monochromatic, coherent light. A well known source of such light is a laser.

What Light of one wavelength that travels with its crests and troughs aligned is what?

Light waves of a single wavelength is known as being coherent. This allows constructive interference which occurs when two or more waves are in phase i.e. their crests and troughs are aligned.

What is a sentence for wavelength?

The wavelength of a transverse wave is the distance between adjacent crests or troughs (peaks or valleys).


What is the definition of the wavelength of light?

The wavelength of light is the distance between two consecutive peaks or troughs in a light wave. It is a measure of the length of one complete cycle of the wave.


What is one wavelength of light?

The laser light is the type of light that only has one wavelength in its phase. Coherent light is light that has a single frequency and wavelength, and can be described with a single wave equation.


What is the approximate wavelength?

The approximate wavelength is the distance between consecutive peaks or troughs of a wave. It is commonly measured in meters and is inversely related to the frequency of the wave through the speed of light equation (wavelength = speed of light / frequency).


What are the Frequency and wavelength of visible light?

Light is measured by its wavelength (in Hertz). Wavelength approaches the separation between two progressive wave peaks or troughs. Frequency is the number of peaks or troughs per unit of time.


What is the definition of wavelength in units?

the distance between two consecutive compressions or rarefactions of a light wave is called its wavelength.


When is the only time that light travels at the speed of light?

Light always travels at the speed of light, although that's a different number in different substances.


What happens to wavelength of light when in travels in a narrow tube narrower in diameter than the wavelength?

It grows a penis on its nose


What does a wavelength look like and how does it affect the properties of light?

A wavelength is the distance between two peaks or troughs of a wave. In terms of light, a wavelength determines its color. Shorter wavelengths appear blue or violet, while longer wavelengths appear red or orange. The wavelength of light also affects its energy and ability to interact with matter.


Does wavelength measure depth distance energy speed volume or time?

Wavelength is a measure of depth/distance - namely the distance between peaks or troughs in a wave. For light this is referring to peaks/troughs of signal strength. Because the front velocity of a photon of light is always constant (ALWAYS, WITH RESPECT TO ALL FRAMES OF REFERENCE IN THE UNIVERSE, NO EXCEPTIONS), the wavelength of a photon is also a direct measure of it's energy.
