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.
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.
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.
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.
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.
The number of bright fringes in an interference pattern depends on the specific setup and conditions of the experiment. It is determined by factors such as the wavelength of light, the distance between the sources of light, and the distance to the screen where the pattern is observed. The formula for calculating the number of bright fringes is given by n (dsin)/, where n is the number of bright fringes, d is the distance between the sources, is the angle between the sources and the screen, and is the wavelength of light.

the light must be coherent - which happens when a single beam of light is split
In the interference diffraction phenomenon, the relationship between the ratio of the distance between two slits and the screen (d) to the wavelength of light () determines the pattern of interference fringes observed on the screen. This relationship affects the spacing and intensity of the fringes, with smaller ratios leading to wider spacing and more distinct fringes.
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.
Laser light has a single wavelength and is coherent, allowing for a well-defined interference pattern to be created easily. In contrast, Na-light contains multiple wavelengths and is not as coherent, making it more difficult to generate clear interference fringes.
In an interference pattern, maxima occur at points where the path difference between two waves is an integer multiple of the wavelength (nλ, where n is an integer). Conversely, minima occur where the path difference is an odd multiple of half the wavelength ((n + 0.5)λ). Additionally, constructive interference leads to bright fringes (maxima), while destructive interference results in dark fringes (minima). These conditions apply in contexts such as double-slit experiments and thin-film interference.
When the separation of slits in a double-slit experiment is doubled, the interference pattern on the screen will show more distinct and sharper interference fringes. This is because the increased distance between the slits creates a larger phase difference between the waves that enhances the interference effects.
The number of bright fringes in an interference pattern created by two coherent light sources is determined by the formula: ( N fracd cdot lambdaD 1 ), where ( N ) is the number of bright fringes, ( d ) is the distance between the two sources, ( lambda ) is the wavelength of the light, and ( D ) is the distance from the sources to the screen.
