Find number of fringes separated by 1 cm on a screen at a distance of 2mm from slits which are 0.2mm apart from each other.The wavelength of light used is 500nm.
Homework Equations
The Attempt at a Solution
I really don't know any way to solve it.I have tried putting unit values of slit distance wavelength and screen distance but I am not sure if that can be applied here

Then by dividing 1cm by fringe width you will get the numberAbhimessi10 said:Ok then?

The number of fringes in a Young's Double Slit Experiment (YDSE) is determined by the formula n = d*sin(theta)/lambda, where n is the number of fringes, d is the distance between the two slits, theta is the angle of incidence, and lambda is the wavelength of light.
The number of fringes in a YDSE increases as the distance between the slits increases because the distance between the fringes is directly proportional to the distance between the slits. As the distance between the slits increases, the overall distance between the fringes increases, resulting in a higher number of fringes.
The number of fringes in a YDSE does not change when a different color of light is used. This is because the number of fringes is determined by the wavelength of light, which remains constant for a given material. However, the spacing between the fringes may change as different colors of light have different wavelengths.
Yes, the number of fringes in a YDSE can be altered by changing the distance between the light source and the slits. This is because the angle of incidence, theta, is affected by the distance between the light source and the slits. As theta changes, the number of fringes changes accordingly.
The number of fringes in a YDSE will differ when using monochromatic vs. white light. Monochromatic light, which consists of a single wavelength, will produce a clear and distinct pattern of fringes. White light, on the other hand, is made up of multiple wavelengths and will produce overlapping patterns of fringes, making it more difficult to count the exact number of fringes.
