Can two bulbs act as coherent sources?
No, the two independent bulbs will not act as coherent sources because they won’t possess stable constant phase difference.
Can you obtain coherent sources from two separate sources?
Yes. In fact, only coherent sources have any phase relationships.
Can two independent sources of light be coherent?
Two sources are said to be coherent if they have the same wavelength as well as the same frequency. Therefore, the sources can maintain the phase difference of their waves being constant or zero. Hence, two independent sources of light can not be coherent.
Why can’t we produce two different coherent sources of light from two different sources off light?
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 different bulbs?
No, because the light waves emitted by two independent bulbs will not have stable constant phase difference.
What are the conditions for two sources to be coherent?
Two sources are said to be coherent when the waves emitted from them have the same frequency and constant phase difference.
What are two coherent sources of light Why are they said to be coherent?
Answer: Two sources of light are said to be coherent when both give out light waves of the same wave length and constant phase difference.
Can two independent monochromatic sources of light be 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.
Can two monochromatic sources of light be coherent?
Wave Optics. (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 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.
Can two sodium Vapour lamps ie two independent monochromatic sources of light act as coherent sources explain in brief?
Yes, two sources which emit light of same wavelength, same frequency and equal intensity or amplitude in the same direction are coherent sources.
