Why is it necessary that two sources must be coherent to produce sustained interference?
For sustained interference, the waves from both sources must have constant phase relationship. This is because interference patterns result from the constructive and destructive superposition of waves. If the waves are not in phase, the interference will be sporadic and not sustained.
What else can I help you with?
Can coherent sources produce interference explain?
Yes, coherent sources can produce interference when the waves emitted from the sources have a constant phase difference and match in frequency and wavelength. This results in the waves either reinforcing (constructive interference) or canceling out (destructive interference) each other, leading to a pattern of alternate bright and dark areas.
Why are coherent sources required to produce interference of light?
Coherent sources are required to produce interference of light because they have a constant phase difference between them. This phase relationship allows the light waves to either reinforce or cancel each other out, creating distinct interference patterns. Incoherent sources have random phase relationships, leading to a lack of interference effects.
What are examples of coherent sources?
Examples of coherent sources include lasers, superluminescent diodes, and optical fibers. These sources produce light waves that are in phase with each other, leading to interference patterns and constructive interference.
What are the conditions two light sources to be coherent?
Two light sources are considered coherent if they have a constant phase difference between them and the same frequency. This allows for constructive interference to occur and produce a stable interference pattern. Additionally, the light sources should have similar polarization and be from the same spectral line.
What does coherent mean in physics?
In physics, coherent refers to the characteristic of waves that are in phase with each other, meaning they have a constant phase relationship. When waves are coherent, they can produce constructive interference patterns, resulting in a stronger overall signal. Coherence is important in areas such as optics and quantum mechanics.

Light of a single wavelength and having all waves in phase is?
called coherent light. This light can produce interference patterns and is commonly produced by lasers due to its focused and efficient properties.

What is a coherent light?
Coherent light is light where all the electromagnetic waves oscillate in phase with one another. This results in a uniform, well-defined wavefront that enables interference patterns to be produced, such as those seen in lasers. Coherent light sources are characterized by their ability to produce a narrow beam with a consistent wavelength and direction.
Why two distant flash lights will not produce an interference pattern?
Two distant flashlights will not produce an interference pattern because the distance between them is too large for the light waves to interact and interfere with each other. The interference is only noticeable when the distance between the sources is comparable to the wavelength of the light.
Why two distant flash lights do not produce interference fringes?
Interference fringes are produced when waves from separate sources overlap and interfere with each other. In the case of two distant flashlights, the waves emitted by each flashlight do not overlap significantly at a distance, so interference fringes are not observed. Additionally, the coherence length of the light emitted by the flashlights may be too low to produce visible interference fringes at a long distance.
What are the condition for good interference pattern?
Good interference patterns are achieved when the two sources emit coherent waves of the same frequency and amplitude. The sources should be close enough to create interference, but far enough to avoid diffraction effects. Additionally, the waves should have a consistent phase relationship to produce clear and distinct interference fringes.
What is a device that produce coherent light?
The name of the device that produces coherent light is LASER.
Uses of fresnel's biprism?
Fresnel's biprism is commonly used in experiments to study interference and diffraction of light. It can be used to produce interference fringes, measure the wavelength of light, and study wavefront properties. Additionally, it is used in optical systems for generating coherent light sources.
