Light is emitted due to the de-excitaton of electrons from higher orbits of the various atoms of the light source.The de-excitation can also be to different levels in different atoms resulting in emission of different wavelengths.A light source will have numerous atoms in it.When you take two light sources it is not possible for all the atoms to get de-excited to the same shell at the same time(causing phase difference) that is why two independent sources cannot be coherent.
The characteristic of the current sources is that it cannot operate in an pen circuit.
It cannot be known for certain what will and will not be available in 2050. Speculation suggests at the present rate some fossil fuels will be almost exhausted and we may or may not have fusion power. Some form of fission will be available as will solar and other renewable sources.
There is no correlation. It is true in some cases and false in others. Trust me ... During my so-called career in that profession, I have encountered a substantial population of engineers none of whom could write two coherent sentences to save his life, let alone a 'paper'.
This is an extremely complex topic that cannot be answered here. You need to learn how to create dependency rules in the 'make' language. Suggested sources include the O'Reilly books on 'make'.
Right now, coal and nuclear plants are the main sources of power. There are currently many efforts to shift this to renewable energy sources such as geothermal energy, solar energy, etc. The main reason for why renewable energy sources are currently not the main source is because their output cannot be adjusted during peak hours or other times of higher demand. In many cases, renewable energy plants are more expensive to operate as well. As for non-renewable energy sources, coal and nuclear plants can simply adjust their output during peak hours. The wind may die down or a storm may block the sun during peak hours, reducing the effectiveness of renewable power.
to produce interference pattern the sources should be coherent but two independent sources cannot produce such pattern. hence they won't produce interference fringes
Coherent light (like a laser) is a single frequency. Polychromatic light is, by definiation, multiple frequencies and cannot be coherent.
If you don't know how to write a coherent argument, you cannot win your cases!
it has no independent locomotion - it cannot move by itself
When you cannot find any other sources that supports its arguments.
Only an independent clause can stand independently. A dependent clause is dependent on an independent clause.
A Paragraph that cannot stand on its own.
Theoretically it cannot as destructive interference between incoherant wave trains occur (i.e. photons are released spontaneously)
Independent and dependent are types of variables. These variables are used mostly in science and math. When using independent variables you can control them dependent variables you cannot.
When men are ignored by women, they may experience feelings of rejection or frustration. They may try to seek attention through different means, such as increased efforts to gain the woman's attention or becoming aloof in response. Some men may also internalize their feelings and reflect on their actions to understand why they are being ignored.
how to make money, how to be independent
A state cannot be an independent republic and also part of the United States.If you are asking, "What is the only state that was oncean independent republic",the answer is "Texas".
