What is a coherent sentence?
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.
Why is coherent light useful?
For other applications, the coherence of the light used should be as low as possible. 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 Sun a coherent source?
Incoherent light, such as sunlight from a cloudy sky, and coherent light from a laser, are each limiting theoretical constructs. Even though the sun is considered to be an incoherent source, sunlight has enough coherence to impart speckle to the image formed in a microscope.
Why are lasers Coherent?
Laser radiation is highly coherent, which means the waves of light emitted have a constant relative phase. The waves of light in a laser beam are thought of as in phase with one another at every point. The degree of coherence is proportional to the range of wavelengths in the light beam, or the beam’s monochromaticity.

Is a laser 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.
What is coherent communication skills?
The term coherence refers to the smooth flow of ideas in a text. There are two main strategies that will make your writing coherent: organizing your ideas in a logical order, and connecting them effectively by using transition words and phrases.
Why coherence is important in writing?
Coherence is an essential quality for good academic writing. In academic writing, the flow of ideas from one sentence to the next should be smooth and logical. Without cohesion, the reader will not understand the main points that you are trying to make. It also hampers readability.
What is meant by coherent source?
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 is coherence in reading and writing?
Coherence refers to the general sense that a text makes sense through the organisation of its content. In writing, it is provided by a clear and understood structuring of paragraphs and sentences in writing. A learner’s argument essay is coherent because it has a structure that gives unity and follows an accepted form.
Why is stimulated emission coherent?
In laser action the stimulating emission triggers a chain reaction in which the radiation from one atom stimulates another in succession until all the excited atoms in the system have returned to normalcy. In doing so, coherent monochromatic light (light of a single wavelength) is emitted.
