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?

please show all work wavelength 450 nm? 8. Monochromatic light illuminates two parallel slits 0.2 mm apart. On a screen I m away from the slits, the first bright fringe is separated from the central fringe by 2.5 mm. Find the wavelength of the light. C
A laser beam ( - 632.6 nm) is incident on two slits 0.200 mm apart. How far apart are the bright interference fringes on a screen 5 m away from the double slits? cm 2. (-/10 Points) DETAILS SERCP7 24.P.002. MY NOTES PRACTICE ANOTHER In a Young's double-slit experiment, a set of parallel sits with a separation of 0.050 mm is illuminated by light having a wavelength of 593 nm and the interference pattern observed on a screen 3.50 m...
A laser emits light at a wavelength of 488 nm at an average power of 5.00 mW. The laser’s produces a circular beam with a diameter of 1.00 mm. This light is then passed through a double slit projecting an interference pattern on a screen 2.25 m away. a. (10 points) If the central bright fringe is 3.50 cm wide, what is the spacing between the slits?
Question 6 (1 point) Laser light of wavelength 633 nm falls onto a double slit with slit separation 0.132 mm. An interference pattern is observed on a screen 2.20 m away. How far apart are the bright spots on the screen near the middle of the pattern? 1.51 cm 1.33 cm 1.06 cm 1.66 cm 0.960 cm
Light of wavelength 660 nm falls on two slits and produces an interference pattern in which the third-order bright red fringe is 34 mm from the central fringe on a screen 2.8 m away. What is the separation of the two slits? d= ??
Light of wavelength 500 nm falls on two slits and produces an interference pattern in which the third order bright fringe is 45 mm from the central fringe on the screen 2.0 m away. What is the distace between two slits? Give answer in mm.
A laser beam of wavelength 600 nm falls on a grating having 4000 lines per cm. If the screen is 2.00 m away from the grating, how far apart will be the two first order images. (The answer says it is .98m but I got .49m and I have no clue what I did wrong.)
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?
Laser light of wavelength 633 nm falls onto a double slit with slit separation 0.132 mm. An interference pattern is observed on a screen 2.20 m away. How far apart are the bright spots on the screen near the middle of the pattern?
Two narrow slits are illuminated by a laser with a wavelength of 541 nm. The interference pattern on a screen located x = 4.60 m away shows that the third-order bright fringe is located y = 8.60 cm away from the central bright fringe. Calculate the distance between the two slits. a.) 8.68×10-3 cm The screen is now moved 2.3 m further away. What is the new distance between the central and the third-order bright fringe? b.) ????
