Are monochromatic sources coherent?

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.

Is two monochromatic source can produce interference?

Two independent monochromatic sources are not coherent. Hence, they cannot produce a sustained interference pattern.

How can monochromatic light be made coherent?

Laser light is a source of coherent monochromatic light. Coherence – two waves are coherent if the phase difference between them is constant. For this to be the case they must have the same frequency. Monochromatic – means having only one wavelength of light present.

What is the difference between coherent and monochromatic?

Coherent light must have the same phase as well as the same frequency. Monochromatic light only has to have the same frequency. A coherent source is always monochromatic but a monochromatic source may or may not be a coherent source.

Can non monochromatic light be coherent?

There’s some subtleties around the edges of this question, but the short answer is yes. Non-monochromatic light is made up of some combination (which might be coherent or incoherent) of light of a range of different frequencies.

Why are two 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.

Can two independent monochromatic sources of light be coherent explain?

(a) (i) Light waves, originating from two independent monochromatic sources, will not have a constant phase difference. Therefore, these sources will not be coherent and, therefore, would not produce a sustained interference pattern.

What is difference between monochromatic and coherent?

What are coherent sources physics?

In physics, two wave sources are coherent if their frequency and waveform are identical. Coherence is an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference. Two waves are said to be coherent if they have a constant relative phase.
