In Young's experiment a mixture of orange light (611 nm) and blue light (471 nm) shines on the double slit. The centers of the first- order bright blue fringes lie at the outer edges of a screen that is located 0.392 m away from the slits. However, the first-order bright orange fringes fall off the screen. By how much and in what direction (toward or away from the slits) should the screen be moved, so that the centers of the first-order bright orange fringes just appear on the screen? It may be assumed that is small, so that sin ( is approximately equal to tan , and the sign "+" means that the screen moves toward the slits.

In a double-slit experiment the distance between slits is 3.8 mm and the slits are 1.1 m from the screen. Two interference patterns can be seen on the screen: one due to light of wavelength 470 nm, and the other due to light of wavelength 570 nm. What is the separation in meters on the screen between the m = 3 bright fringes of the two interference patterns?

Fringes in the Thomas Young experiment are produced using sodium light of wavelength 513 nm and two slits which are 1.2 mm apart. If the fringes are formed on a screen 1.1 m away from the slits, how far is the third order bright fringe from the middle of the screen? Give your answer in millimeters (mm)

An instructor directs monochromatic light toward a single slit in an opaque barrier. The light has a wavelength of 550 nm and the slit is 0.225 mm wide. The light that passes through the slit creates a diffraction pattern on a screen, which is 1.20 m from the slit. (a) How wide (in mm) is the central maximum (the central, bright fringe), as measured on the screen? mm (b) How wide (in mm) is either of the two first-order bright fringes, as measured on the screen? mm

A laser beam is normally incident on a single slit with width 0.580 mm. A diffraction pattern forms on a screen a distance 1.20 m beyond the slit. The distance between the positions of zero intensity on both sides of the central maximum is 2.12 mm. Calculate the wavelength of the light (in nm). X Find the relationship among y, the distance from the central maximum to the first minimum, L, and 0, and then apply the equation for the Fraunhofer diffraction pattern. Solve for A. Hint: use a small-angle approximation. nm

In a Young's double-slit experiment, a set of parallel slits with a separation of 0.108 mm is illuminated by light having a wavelength of 584 nm and the interference pattern observed on a screen 3.50 m from the slits. (a) What is the difference in path lengths from the two slits to the location of a third order bright fringe on the screen? answer in ?m (b) What is the difference in path lengths from the two slits to the location of the third dark fringe on the screen, away from the center of the pattern? answer in ?m

A scientist directs monochromatic light toward a single slit in an opaque barrier. The light has a wavelength of 520 nm and the slit is 0.190 mm wide. The light that passes through the slit creates a diffraction pattern on a screen, which is 1.60 m from the slit. How wide (in mm) is the central maximum (the central, bright fringe), as measured on the screen? How wide (in mm) is either of the two first-order bright fringes, as measured on the screen?

An instructor directs monochromatic light toward a single slit in an opaque barrier. The light has a wavelength of 550 nm and the slit is 0.230 mm wide. The light that passes through the slit creates a diffraction pattern on a screen, which is 1.65 m from the slit. (a) How wide (in mm) is the central maximum (the central, bright fringe), as measured on the screen?  Single-slit diffraction is most readily described with a formula that gives the distance from the center of the pattern to the mth-order dark fringe. Consider the first dark fringe on either side of the central peak  (m = ±1).  How does its distance relate to the full width of the central maximum? Take care with units. mm (b) How wide (in mm) is either of the two first-order bright fringes, as measured on the screen?  Single-slit diffraction is most readily described with a formula that gives the distance from the center of the pattern to the mth-order dark fringe. Consider two adjacent fringes on one side of the…

In an interference experiment using a monochromatic source emitting light of wavelength λ=600 nm, the fringes are produced by two long, narrow slits separated by a distance 'd' mm. The fringes are formed on a screen which is situated at a distance 7 m from the slits. Determine 'd', if the fringe width w==6 mm.
