What is an example of coherent?

The definition of coherent is sticking together or easy to understand. A group of people who vote the same way is an example of coherent. A person who speaks clearly and makes sense is an example of coherent.

What is mean by coherent sources?

In physics, two wave sources are perfectly coherent if their frequency and waveform are identical and their phase difference is constant. Two waves are said to be coherent if they have a constant relative phase.

What are coherent sentences?

If a paragraph is coherent, each sentence flows smoothly into the next without obvious shifts or jumps. A coherent paragraph also highlights the ties between old and new information to make the structure of ideas or arguments clear to the reader.

What part of speech is coherent?

What does coherent light mean?

Two beams of light are coherent when the phase difference between their waves is constant; they are noncoherent if there is a random or changing phase relationship. …

Why is coherent light useful?

Importance of Coherence in Applications Some applications need light with very high spatial and temporal coherence. A low degree of temporal coherence can also be beneficial for laser projection displays, imaging and pointer applications, as it reduces the tendency for laser speckle and similar interference effects.

Is LED light coherent?

Unlike a laser, the light emitted from an LED is neither spectrally coherent nor even highly monochromatic. However, its spectrum is sufficiently narrow that it appears to the human eye as a pure (saturated) color.

How is coherent light produced?

A laser produces coherent light through a process known as STIMULATED EMISSION. You may know that light is the result of spontaneous emission of a photon by an electron undergoing a transition in an atom. They all have the same phase…so laser light is highly coherent.

Can two independent sources of light be coherent?

Answer: Two independent sources of light cannot be coherent. This is because light is emitted by individual atoms, when they return to ground state. Even the smallest source of light contains billions of atoms which obviously cannot emit light waves in the same phase.

How is laser light coherent?

The light from a laser is said to be coherent, which means the wavelengths of the laser light are in phase in space and time. These three properties of laser light are what make it more of a hazard than ordinary light.
