the light must be coherent - which happens when a single beam of light is split

How will decreasing the wavelength of light affect the fringe spacing in an interference pattern?
Decreasing the wavelength of light will decrease the fringe spacing in an interference pattern. This is because fringe spacing is directly proportional to the wavelength of light used in the interference pattern.
1 If a longer wavelength of light is used in an interference pattern do the fringes have a bigger separation?
Yes, when a longer wavelength of light is used in an interference pattern, the fringes will have a bigger separation. This is because the fringe separation is directly proportional to the wavelength of the light used in the interference pattern.
What effect does an increase in the wavelength have on the interference pattern?
An increase in wavelength will cause the interference fringes to spread out since the distance between the fringes is directly proportional to the wavelength. This results in a larger separation between the bright and dark regions in the interference pattern.
Why we use slit width comparable to the wavelength in interference?
Using a slit width comparable to the wavelength in interference experiments helps to maximize the diffraction effects, leading to better-defined interference patterns. This ensures that the interference fringes are well-resolved and allows for accurate measurements of parameters like wavelength or slit separation. Additionally, using a narrower slit width can enhance the contrast and visibility of the interference pattern.
How does interference pattern change when wavelength of light is used?
Shorter wavelengths produce interference patterns with narrower fringes and greater separation between them, while longer wavelengths produce interference patterns with wider fringes and smaller separation between them. The spacing of fringes is proportional to the wavelength of light.

How does the interference pattern change as the wavelength changes?
As the wavelength increases, the interference fringes become more spread out and the distance between them increases. Conversely, as the wavelength decreases, the interference fringes become more closely packed together. The specific pattern will depend on the ratio of the wavelength to the distance between the two slits.
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.
How does the distance between consecutive bright fringes depend on the wavelength of the light?
The distance between consecutive bright fringes in a double-slit interference pattern depends on the wavelength of the light. Specifically, the distance increases as the wavelength of the light increases.
Monochromatic light passes through 2 parallel slits forms an interference pattern on screen As the distance between the 2 slits is decreased the distance between light bands in the pattern?
The distance between the light bands in the interference pattern increases when the distance between the two slits is decreased. This is because decreasing the distance between the slits results in a larger angle of diffraction, leading to a wider spacing between the interference fringes on the screen.
What is the value of the thickness of wire using He-Ne laser?
The value of the thickness of wire using a He-Ne laser can be determined by measuring the interference pattern produced when the laser light is reflected off the wire. By analyzing this interference pattern, the thickness of the wire can be calculated based on the wavelength of the laser light and the angles at which the interference occurs.
What is a reason of no interference pattern?
interference happens if and only if the waves entering the double slits are synchronous (having same nature and same wavelength) and coherent (waves between the two waves are constant at anytime i.e. starting at the same time)... so if these conditions are valid, interference occurs, otherwise no interference will happen.
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.
