2. At most, how many bright fringes can be formed on either side of the central bright fringe when light of wavelength 670 nm falls on a double slit whose slit separation is 3.70 x 10-º m?

Two slits spaced 0.15 mm apart are placed 75.0 cm from a screen. An interference pattern is observed on the screen with adjacent bright fringes spaced 2.75 mm apart. What is the wavelength of the light? (Give your answer in nm.)

3. A physics instructor wants to produce a double-slit interference pattern large enough for her class to see. Forthe size of the room, she decides that the distance between successive bright fringes on the screen should be atleast 2.00 cm. If the slits have a separation d = 0.0220 mm, what is the minimum distance from the slits to thescreen when 632.8-nm light from a He–Ne laser is used?

Light with wavelength 442 nm passes through a double- slit system that has a slit separation d =0.400 mm. Determine how far away a screen must be placed so that dark fringes appear directlyopposite both slits, with only one bright fringe between them. (L = 36.2 cm)

Light of wavelength 628 nm passes through a slit 6.40 × 10-6 m wide and falls on a screen that is 2.69 m away. What is the distance on the screen from the center of the central bright fringe to the third dark fringe on either side?

345 nm light incident on a 0.364-mm wide single slit produces a vertically-oriented diffraction pattern on a screen 3.43 m away. Determine the approximate ratio of the intensity I at a point 2.04 mm above the center of the central maximum to the intensity Io of the central maximum itself. I Io ≈ 0.2369 Incorrect

1)A red low-power laser with λ = 634nm was beamedat a double-slit grating. An interference patternappeared on a screen 2.50 m from the grating. Thedistance from central spot to the next bright spotwas 22.5cm.What is the spacing between the slits in the grating? 2. The red laser (in Q1) is replaced by a blue laserwith a shorter wavelength. All else is the same.Show mathematically whether the interferencepattern it produces will place the bright spots closeror further apart. 3.Given that the blue laser in Q2 has a wavelength of445 nm, calculate the “spot-spacing” for the sameslit grating and screen distance as in Q1. 4.A green laser beam produces spots which are0.334m apart (central to m=1) when a grating is usedwith slits 3,000 nm apart and a screen 1.90m away.What is the wavelength of the laser light?

Due to the wave nature of light shines on a single slit will produce a diffraction pattern. Green light 505nm is shined on a slit with width 0.490nm. a) find the width of the central maximum located 1.50 m from the slit in mm b) what is the width of the first order fringe in mm

A single slit is illuminated with 610-nm light, and the resulting diffraction pattern is viewed on a screen 2.3 m away. (a) If the linear distance between the first and second dark fringes of the pattern is 12 cm, what is the width of the slit? (b) If the slit is made wider, will the distance between the first and second dark fringes increase or decrease? Explain.
