In a Young's Slit experiment a wavelength of 589 nm is used and intensity maxima and minima are observed on screen one metre from the slits. A total of 7 maxima are observed on the screen, with the outer lying at +-1.886 m from the central axis. What is the slit separation?
here the conditin is y = m*lamda*L/d
y = distance form central maximum to 7th central maximum
lamda = wavelength of light used = 589 nm
m = 7
L = 1 m
d = slit seperation
d = m*lamda*L/y = (7*589*10^-9*1)/(1.886) = 2.186*10^-6 m = 2.186 micro meter

In a Young's double-slit experiment, 625-nm-wavelength light is sent through the slits. The intensity at an angle of 2.40° from the central bright fringe is 83% of the maximum intensity on the screen. What is the spacing between the slits?
In a Young's double-slit experiment, 586 -nm-wavelength light is sent through the slits. A screen is held at a distance of 1.50 m from the slits. The second-order maxima appear at an angle of 2.50° from the central bright fringe. How far apart do the first-order (m=1) and second-order (m=2) maximum appear on the screen?

A 589 nm wavelength light shines on a slit 1.00 mm wide. The diffraction pattern is projected on a screen 3.00 m from the slit. What is the distance between the first and second diffraction minimas? (Note: both minima are the same side of the central maxima.) (1.77 mm)
a) Young's double-slit experiment is performed with 595-nm light and a distance of 2.00 m between the slits and the screen. The tenth interference minimum is observed 7.40 mm from the central maximum. Determine the spacing of the slits (in mm). Answer: 1.5277 mm (b) What If? What are the smallest and largest wavelengths of visible light that will also produce interference minima at this location? (Give your answers, in nm, to at least three significant figures. Assume the visible...
