I want the right answer it is my thired time to post it?? answer 3.6 and 018 not correct
Here ,
D = 77 cm = 0.77 m
wavelength = 589 nm
for the width of slit
for the distance between dark fringes
(2.50 - 1) * 10^-3 = 2 * 589 *10^-9 * 0.77/d
solving for d
d = 0.605 mm
the slit width is 0.605 mm

Light from a sodium lamp (lambda = 589 nm) illuminates a narrow slit and is observed on a screen 77.0 cm behind the slit. The distance between the first and third dark fringes is 2.50 mm What is the width (in mm) of the slit?
The two most prominent wavelengths in the light emitted by a helium discharge lamp are 686.7 nm (red) and 587.6 nm (yellow). Light from a helium lamp illuminates a diffraction grating with 750 lines/mm, and the light is observed on a screen 50 cm behind the grating. What is the distance between the first-order red and yellow fringes? Express your answer in cm.
I think this is a single slit diffraction, but I need help Light from an argon laser produces light at lambda = 515 nm. This light is used to form a diffraction pattern through a diffraction grating with slit spacing of 2 mu m. The interference pattern is observed on a screen 0.7 m behind the slits. Draw a picture to show both a & b: a. What's the maximum number of bright fringes that could be observed. b. What...
The two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656 nm (red) and 486 nm (blue). Light from a hydrogen lamp illuminates a diffraction grating with 550 lines / mm, and the light is observed on a screen 1.2 m behind the grating.You may want to review (Page 940).For general problem-solving tips and strategies for this topic, you may want to view a Video Tutor Solution of Diffraction grating.Part AWhat is the distance between...
Please use pdf scanner for answer. Please Be neat and clear. Only answer if sure of answer. Thanks! (: Violet light (wavelength 380 nm) falls on a narrow slit that produces a diffraction pattern on a screen 5.0 m away. The width of the central maximum is 3.7 mm. a.) How does this width change if the violet light is replaced with a red light (wavelength 690 nm)? b.) What is the width of the slit? c.) What is the...

4) Consider orange light of wavelength 620 nm incident on a double slit. The interference pattern is observed on a screen that is placed 2.50 m behind the slits. Nine bright fringes are seen, spanning a total distance of 45.0 mm. a) What is the fringe spacing between two adjacent fringes? (Be careful, you may want to sketch out a simple picture of the fringes to assist you with this problem!) b) What is the spacing between the two slits?
A helium-neon laser (λ = 633 nm) illuminates a single slit and is observed on a screen 1.60 m behind the slit. The distance between the first and second minima in the diffraction pattern is 4.15 mm . What is the width (in mm) of the slit?
A helium-neon laser (λ = 633 nm) illuminates a single slit and is observed on a screen 1.30 m behind the slit. The distance between the first and second minima in the diffraction pattern is 3.95 mm .What is the width (in mm) of the slit?
A helium-neon laser (λ = 633 nm) illuminates a single slit and is observed on a screen 1.60 m behind the slit. The distance between the first and second minima in the diffraction pattern is 3.65 mm. What is the width (in mm) of the slit?
