A double-slit experiment is performed using a helium-neon laser, with wavelength of 632.8 nm. The slit distance is 0.5 mm, and the distance to the screen is 1.8 m.
What is the width of the central bright fringe?
width = lembda*distance between screen and slit/ distance between slit
width= 632.8*10^-9*1.8/0.5*10^-3
width = 0.00228 m

Define the width of a bright fringe as the distance between the minima on either side. (a) What is the width of the central bright fringe? mm (b) What is the width of the first bright fringe on either side of the central one? mm
Red light of wavelength 633 nm from a helium-neon laser passes through a slit 0.340 mm wide. The diffraction pattern is observed on a screen 2.95 m away. Define the width of a bright fringe as the distance between the minima on either side. A) What is the width of the central bright fringe? in m B) What is the width of the first bright fringe on either side of the central one? in m
Helium–neon laser light (λ = 632.8 nm) is sent through a 0.250-mm-wide single slit. What is the width of the central maximum on a screen 2.00 m from the slit? mm
4. Helium-neon laser light (λ = 632.8 nm) is sent though a 3.3 mm wide single slit. A viewing screen is placed a distance L from the single slit. Choose the correct answer On the viewing screen (a) a bright fringe is observe in the center with alternating dark and bright fringes whose intensity decrease from the center to both sides, (b) a bright fringe is observe in the center with alternating dark and bright fringes with the same intensity...
Coherent light of wavelength 633 nm from a Helium Neon laser falls on a double slit with a slit separation of 0.103 mm. An interference pattern is produced on the screen 2.56 m away from the slits. a) how far from the central maximum is the third interference maximum? b) what about the third interference minimum?
Helium-neon laser light of wavelength 353 nm is sent through a 0.459 mm wide single slit. What is the width of the central maximum on a screen 1.22 m from the slit?
Young's experiment is performed with light of wavelength 502 nm from excited helium atoms. Fringes are measured carefully on a screen 1.50 m away from the double slit, and the center of the 20th fringe (not counting the central bright fringe) is found to be 11.6 mm from the center of the central bright fringe. What is the separation of the two slits?
You perform a double-slit experiment in order to measure the wavelength of the new laser that you received for your birthday. You set your slit spacing at 1.11 mm and place your screen 8.43 m from the slits. Then, you illuminate the slits with your new toy and find on the screen that the tenth bright fringe is 4.87 cm away from the central bright fringe (counted as the zeroth bright fringe). What is your laser's wavelength 1 expressed in...
3. A double slit experiment uses a laser with a wavelength of 633 nm and a slit separation of 120 um The fringes are observed on a screen at a distance of 100 mm. The experiment is performed in air and then repeated under water (n 1.33). a. What is the fringe spacing in air? b. What is the fringe spacing under water? c. When a thin sheet of plastic (n 1.91) is placed over one of the slits in...
A single slit diffraction experiment performed with an argon laser of wavelength 454.6 nm produces a pattern on a screen with dark fringes (minima) separated by 10 mm. If we switch to a helium laser of wavelength 632.8 nm, without changing anything else in the setup, what will be the new separation between dark fringes? Select one: a. 13.9 mm b. 7.2 mm c. 15.2 mm d. 17.3 mm e. 6.1 mm
