The change in light fringes is caused by the phenomenon of interference. When light passes through two slits, it diffracts and creates a pattern of constructive and destructive interference, resulting in light and dark fringes. When the intensity of one slit is reduced, the amount of light passing through that slit decreases, altering the interference pattern and causing a change in the light fringes.
The intensity of the light fringes is directly related to the intensity of the light passing through the slits. Therefore, reducing the intensity of one slit will also reduce the overall intensity of the light fringes. This is because less light is available for interference, resulting in a decrease in the brightness of the fringes.
Yes, changing the intensity of one slit will affect the number of light fringes observed. The number of fringes is determined by the wavelength of light and the distance between the slits. When the intensity of one slit is reduced, the interference pattern changes, leading to a change in the number of fringes observed.
The width of the slits can also affect the change in light fringes when the intensity of one slit is reduced. If the slits are very narrow, the fringes will be closer together and the change in intensity of one slit will have a more noticeable effect on the overall interference pattern. On the other hand, wider slits will result in wider fringes and a smaller change in intensity will be observed.
Yes, the change in light fringes can be used to determine the relative intensity of the light passing through each slit. By measuring the change in the interference pattern, the relative intensities can be calculated using mathematical equations. However, the absolute intensities cannot be determined without additional information about the light source and the experimental setup.
