What is the effect of decreasing the widths of slits in double slit experiment?
The double slit experiment is a classic experiment in physics that demonstrates the wave-particle duality of light and other quantum particles. It involves shining a beam of light through two parallel slits and observing the interference pattern that is formed on a screen placed behind the slits.
When the widths of the slits are decreased, the interference pattern on the screen becomes more spread out and the fringes become less defined. This is because decreasing the widths of the slits reduces the amount of diffraction, which is the bending of light as it passes through the slits.
Decreasing the widths of the slits decreases the intensity of the interference pattern, meaning that the bright and dark fringes will become less distinct. This is because the narrower the slits, the less light is able to pass through and create the interference pattern on the screen.
The distance between the fringes on the screen is inversely proportional to the widths of the slits. This means that as the widths of the slits are decreased, the distance between the fringes will increase. Conversely, if the widths of the slits are increased, the distance between the fringes will decrease.
Decreasing the widths of the slits causes the overall pattern on the screen to become more spread out and less defined. This is because the narrower the slits, the more diffraction occurs, which leads to a broader interference pattern on the screen.
