Two parallel slits are illuminated by light composed of two wavelengths. One wavelength is λA = 657 nm. The other wavelength is λB and is unknown. On a viewing screen, the light with wavelength λA = 657 nm produces its fifth-order bright fringe at the same place where the light with wavelength λB produces its sixth dark fringe. The fringes are counted relative to the central or zeroth-order bright fringe. What is the unknown wavelength in nm?

Two parallel slits are illuminated by light composed of two wavelengths. One wavelength is AA-572nm. The other wavelength is Ag and is unknown. On a viewing screen, the light with wavelength 1-572nm produces its third-order bright fringe at the same place where the light with wavelength As produces its fourth dark fringe. The fringes are counted relative to the central or zeroth-order bright fringe. What is the unknown wavelength? Number i Units
PRINTER VERSION BACK NEXT Chapter 27, Problem 06 GO Interactive Leaming Ware 27.1 provides some pertinent background information for this problem. Two parallels are uminated by light composed of two wavelengths One wavelength is AA 69m. The other wavelength is A and is unknown. On a viewing screen, the light with wavelength 6 produces the order brugt fringe at the same place where the light with wavelength a produces its fourth dark ringe. The fringes are counted relative to the...
19. Two narrow slits are separated by 0.250 mm and illuminated with green light of wavelength 555 nm. The light passes through the slits and shines on a screen 2.00 m behind the slits. 8. If the zeroth order bright tringe falls on the screen at angle 9 -0 radians (straight in front of the slits), at what angle (in radians) does the rst order bright fringe appear?
Ten narrow slits are equally spaced 1.50 mm apart and illuminated with blue light of wavelength 473 nm. The width of bright fringes can be calculated as the separation between the two adjacent dark fringes on either side. Find the angular widths (in rad) of the second- and fourth-order bright fringes. second-order bright fringe rad ____ fourth-order bright fringe rad _____
Ten narrow slits are equally spaced 3.50 mm apart and illuminated with orange light of wavelength 591 nm. The width of bright fringes can be calculated as the separation between the two adjacent dark fringes on either side. Find the angular widths (in rad) of the second- and fifth-order bright fringes.
Two slits are illuminated by light that consists of two wavelengths. One wavelength is known to be 436 nm. On a screen, the fourth minimum of the 436-nm light coincides with the third maximum of the other light. What is the wavelength of the other light?
1. Light of wavelength 640 nm is incident on two slits separated by 0.880 mm. An interference pattern is observed on a screen 2.20 m away. a) Using the small angle approximation (tan θ sinθ), find the distance between the central maximum and the first bright fringe. b) What percent of error is made in locating of the seventh-order bright fringe if the small angle approximation is used compared to using the exact trigonometric function? c) How does the...
In a double-slit experiment, the slits are illuminated by a monochromatic, coherent light source having a wavelength of 517 nm. An interference pattern is observed on the screen. The distance between the screen and the double-slit is 1.3 m and the distance between the two slits is 0.118 mm. A light wave propogates from each slit to the screen. What is the path length difference between the distance traveled by the waves for the fifth-order maximum (bright fringe) on the...
Two narrow slits are illuminated by a laser with a wavelength of 517 nm. The interference pattern on a screen located x = 5.50 m away shows that the fourth-order bright fringe is located y = 9.40 cm away from the central bright fringe. Calculate the distance between the two slits. The screen is now moved 1.7 m further away. What is the new distance between the central and the fourth-order bright fringe?
Two narrow slits are illuminated by a laser with a wavelength of 542 nm. The interference pattern on a screen located x=5.10 m away shows that the fourth-order bright fringe is located y = 6.10 cm away from the central bright fringe. Calculate the distance between the two slits.The screen is now moved 2.4 m further away. What is the new distance between the central and the fourth-order bright fringe?
