Light from a Helium-Neon laser (λ = 633 nm) is incident on a regular array of slits with a slit spacing of a = 1.50 μm and an interference pattern is seen on a screen placed a distance of D = 4.50 m away from the slits, at what distance y from the center of the pattern will the first bright fringe occur? A) 2.10 m B) 3.60 m C) 1.20 m D) 2.40 m
A laser beam is incident on two slits with a separation of 0.195 mm, and a screen is placed 5.15 m from the slits. If the bright interference fringes on the screen are separated by 1.60 cm, what is the wavelength of the laser light? nm
A laser beam is incident on two slits with a separation of 0.230 mm, and a screen is placed 4.90 m from the slits. If the bright interference fringes on the screen are separated by 1.55 cm, what is the wavelength of the laser light? nm
A laser beam is incident on two slits with a separation of 0.180 mm, and a screen is placed 4.90 m from the slits. If the bright interference fringes on the screen are separated by 1.57 cm, what is the wavelength of the laser light? nm
A laser beam is incident on two slits with a separation of 0.215 mm, and a screen is placed 4.95 m from the slits. If the bright interference fringes on the screen are separated by 1.55 cm, what is the wavelength of the laser light? ___ nm
The wavelength of light emitted by a particular laser is 497nm. This laser light illuminates two slits that are 42 um apart. (a) What is the angular separation between the n = 2 and n = -2 maxima? (b) If a screen is placed 1.10 m from the slits, what is the distance between these two maxima? (c) If you want these two maxima to be 1.00 cm apart, how far from the slits do you need to place the...
730 nm light is incident on two narrow, vertical slits of that are 0.43 mm apart. On a screen 4.0 m away, a horizontal pattern of light and dark appears. Describe (and/or draw a diagram) the pattern near the centerline (say, within 10 cm of the point the light would have hit if there were no slits) and calculate the dimensions of the major features of the pattern.
1-A parallel beam of light from a laser with a wavelength 450 nm, falls on a grating whose slits are 1.28 x 10-4 cm apart. How far (in cm) is the 1st order bright spot from the center of the pattern on a screen 3.4 m away? 2-A grating whose slits are 3.2x10-4 cm apart produces a third-order fringe at a 25.0° angle. What is the wavelength of light that is used?
A laser beam with wavelength 632.8 nm is incident on two narrow slits separated by 0.22 mm. Calculate how far apart the resultant interference fringes on a screen will be if it is located 2.3 m away from the slits?
I. Two slits separated by 0.050 mm are illuminated with green light ( 540 nm). The distance between the double slits and the screen is 1.0 m. How many bands of bright lines are there between the central maximum (0) and the 12-cm position (y 12cm)?
