Can you obtain coherent sources from two separate sources?

Can you obtain coherent sources from two separate sources?

Yes. In fact, only coherent sources have any phase relationships.

Can two sources be coherent Why?

No, they are not coherent. The phase difference between the two waves will not be constant. The wavelength and frequency of the waves also will be different.

How can we make two sources coherent?

If the amplitude of an incoming beam of light is divided, then a coherent source can be created. This can be done by the process of partial reflection or refraction. These divided parts further meet with each other to create interference.

Can two sources of light be coherent?

Thus, the phase difference between the waves from the two sources will remain constant. Thus, two sources of light are said to be coherent, when they give light waves of same wavelength and constant phase difference.

What is the phase difference between two coherent sources?

Two sources are said to be coherent, if they emit light waves of same frequency or wavelength and of a stable phase difference ie,ϕ(x)= constant.

Which of the following Cannot produce two coherent sources?

A single prism cannot produce two coherent sources. Hence the answer from the option will be the single prism itself.

What are coherent sources of light why two independent sources Cannot act as coherent sources?

Coherent sources are defined as the sources in the which initial phase difference remains constant. In the case of two independent sources, the initial phase difference cannot remain constant because light is emitted due to millions of atoms and their number goes on changing in a quite random manner.

Can two independent monochromatic sources of light be coherent?

(a) (i) ‘Two independent monochromatic sources of light cannot produce a sustained interference pattern’. Two sources are monochromatic if they have the same frequency and wavelength. Since they are independent, i.e. they have different phases with irregular difference, they are not coherent sources.

What is meant by coherent sources What are the two methods for obtaining coherent sources in the laboratory?

In the laboratory, coherent sources can be obtained by using (1) Lloyd’s mirror and (2) Fresnel’s biprism. Lloyd’s mirror: A plane polished mirror is kept at some distance from the source of monochromatic light and light is made incident on the mirror at a grazing angle.

Why are two independent sources not coherent?

The two independent sources cannot be coherent because of the fact that independent sources cannot maintain a constant phase difference between them. For experimental purposes, two virtual sources obtained from a single parent source can act as coherent.

Why are two light sources not coherent?

Coherent sources of light emit continuous light waves of the same frequency, same wavelength and having either zero or a constant phase difference. Now, (i) 2 Independent sources of light cannot be coherent because: Light is emitted by individual atoms of the source and not by the bulk of matter as a whole.

Which of the following Cannot produce two coherent sources *?

What is the difference between two coherent sources?

Two sources are said to be coherent if they have exactly same frequency and have zero or constant phase difference. Two coherent source cannot be obtained from two different light sources. Was this answer helpful?

What makes two sources of light coherent?

Two sources of light are said to be coherent only if their wavelength/frequency is identical, and are in same phase or at least, have a constant phase difference.

What are the characteristics of a co-Herent source?

Coherent sources have the following characteristics: 1 The waves generated have a constant phase difference 2 The waves are of a single frequency More

Is it possible to create coherent radio waves?

You can actually easily create coherent radio waves because you can control the oscillators with an electronic circuit. There are no completely coherent sources of high frequencies like light and no completely incoherent sources. All sources of light are partially coherent.
