How would the angular separation of interferences fringes in young's double slit experiment change when the distance of separation between the slits and the screen is doubled?
Note that bandwidth = lamda D / d and bandwidth = D @ Here @ is the angular separation. So @ = lamda D / D d = lambda / d So as D is not there in the expression the angular separation remains the same though the distance between slits and the screen is doubled.
What is the discovery of Thomas Young about light?
thomas young carried out his (double slit experiment) where he discussed the interference of light waves using monochromatic light . the 2 slits act as 2 coherent sources which emit light with same amplitude frequency . interference fringes appear due to superposition of light . this experiment is also used to determine the wavelength of monochromatic light. from the relation y=wavelength*distance between 2 slits /distance between the 2 slits and the screen where the fringes appear . where y is the distance between 2 successive bright or dark fringes.
What is the expression for the separation distance between the slits in a double-slit experiment where light waves interfere with each other?
The expression for the separation distance between the slits in a double-slit experiment where light waves interfere with each other is typically denoted by the symbol "d."
How many bright fringes can be observed on a screen in a double-slit interference experiment?
In a double-slit interference experiment, the number of bright fringes observed on a screen is determined by the formula: n (dsin)/, where n is the number of bright fringes, d is the distance between the slits, is the angle of the bright fringe, and is the wavelength of the light.
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.

In young's double slit experiment two slits are made 1mm apart and the screen is placed 1m awaywhat is the fringe separation when blue light of 500cm is used?
The fringe separation can be calculated using the formula: fringe separation = wavelength * distance to screen / distance between slits. For blue light with a wavelength of 500 nm and a distance of 1m to the screen and 1mm between the slits (1mm = 0.1 cm), the fringe separation comes out to be 0.05 mm or 50 micrometers.
What is the expression for fringe width?
The fringe width, often denoted as ( \beta ), in a double-slit interference experiment is given by the formula ( \beta = \frac{\lambda D}{d} ), where ( \lambda ) is the wavelength of the light used, ( D ) is the distance from the slits to the screen, and ( d ) is the distance between the two slits. This expression shows that the fringe width is directly proportional to the wavelength and the distance to the screen, and inversely proportional to the slit separation.

What happens when slit separation is doubled?
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 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 fringe spacing formula used to calculate the distance between interference fringes in a double-slit experiment?
The fringe spacing formula used to calculate the distance between interference fringes in a double-slit experiment is given by the equation: d L / D, where d is the fringe spacing, is the wavelength of light, L is the distance between the double-slit and the screen, and D is the distance between the two slits.
What happens if the distance 'D' between adjacent slits is increased?
Increasing the distance between adjacent slits would result in a narrower interference pattern and wider fringes. This change results in a smaller fringe pattern spread on the screen.
What happens if width of the slits increases in double slit diffraction experiment?
If the width of the slits increases in a double slit diffraction experiment, the fringes will become wider and closer together, resulting in a broader diffraction pattern. This change in the width of the slits will affect the overall intensity and distribution of the interference pattern observed on the screen.
Why narrow slits are taken in Young's double slit interference experiment?
Narrow slits in Young's double slit experiment create a coherent light source, leading to interference patterns. By ensuring the slits are narrow, the light passing through them acts as a coherent wavefront that produces clear interference fringes on the screen. This allows for the observation of the wave nature of light.
