COHERENT WAVES

When the light waves are emitted from a single source and they have the zero phase difference between them then the waves are said to be coherent. The coherent waves are shown below:

For two waves to be coherent both must be having the same frequency and be in phase or having constant phase difference. This is applicable for light as well as sound waves. Hence coheren sound waves.

How do you define coherent waves?

The official definition for the word 'coherent waves' is "a superpositioned wave that does not interfere with other waves in the conductance pathway."


Can waves with different wavelength be coherent?

No. In order to be coherent, the light waves have to be in phase and stay in phase, and the only way for that to happen is for them to have the same wavelength and frequency.


How do you produce a coherent wave?

Coherent waves in the electromagnetic spectrum are produced by masers, for microwaves, and lasers, for light.


What are light waves that moves together as they travel away from their source?

coherent


What is the difference between a monochromatic light and coherent light waves?

The term "mono" refers to a singular object or subject. The term "chrome" refers to colors. The term "monochrome" is a reference to a single color. ie., if two lights are monochromatic that means they have same wavelength. If two waves are monochromatic (having the same wavelength) and are of the same phase, these two waves are defined as coherent waves. Sources generating such waves are known as coherent sources.


How the constructive interference occurs?

coherent waves are waves of the same frequency (same wavelength) and constant phase difference.


Coherent light such as that found in lasers has?

all waves traveling in the same direction.


Light of a single wavelength and having all waves in phase is?

monochromatic, coherent


When two waves of the same wavelength interfere?

If they are coherent, they will add, and vice versa.


What is a term that describes crests and troughs of light waves moving in phase?

Light waves with the same phase and frequency are said to be coherent.


What is light whose waves all have the same wavelength direction and coincidental peaks called?

Coherent
