In a double-slit interference experiment, the light source is a visible laser with wavelength 4.31E-7 m, the distance between slits is 9.51E-4m, and a screen is 2.09 m away from the slits. What is the distance between the central bright fringe and a dark fringe resulting from a 5π phase difference between light from the two slits (in m)?

In a double-slit experiment using light of wavelength 490 nm, the 6th order bright fringe is 38 mm from the central fringe on a screen located 2.2 m from the slits. What is the slit separation?

In the figure, two isotropic point sources of light (5, and S₂) are separated by distance 2.60 um along ay axds and emit in phase at wavelength 920 nm and at the same amplitude. A light detector is located at point Pat coordinate xp on the x axis. What is the greatest value of xp at which the detected light is minimum due to destructive interference? Number Units

Light of wavelength λ = 410 nm is incident upon two thin slits that are separated by a distance d = 25 μm. The light hits a screen L = 2.4 m from the screen. It is observed that at a point y = 4.8 mm from the central maximum the intensity of the light is I = 85 W/m2. Part (a)  Write an equation for the phase shift between the light from the two slits at the observation point in terms of the given variables.   Part (b)  For the given data, what is the phase shift, in radians, between the light from the two slits at the observation point?  Part (c)  What is the intensity of the light at the two slits (I0) in watts per square meter?
