- 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?Given a double slit set up with a spacing of 5.74*10-6m and the light has a wavelength of 618 nm: How far from the central maximum is the third dark fringe (m=2) when the distance between the slits and the screen is 5.00 meters? a) 1.40m b) 2.03m c) 1.30m d) 1.10m (Hint: answer is a)A double-slit system is used to measure the wavelength of light. The system has slit spacing d = 15 μm and slit-to-screen dis- tance L = 2.2m. If the m = 1 maximum in the interference pat- tern occurs 7.1 cm from screen center, what's the wavelength?
- A single slit of width 4.50 x 10 ºm produces a first-order dark fringe at some angle. If the width of the slit is now changed to 3.08 × 10-ºm, a second-order dark fringe is found at three times the previous angle. What is the wavelength of the light?Given a single slit diffraction set up, a slit width of 8.37*10-6m, the screen is 6.00 meters away, and a wavelength of 480 nm, how far away are m=+2 and m=-2 dark fringes?A diffraction grating is 2.30 cm wide and contains 2100 lines. When used with light of a certain wavelength, a third order maximum is formed at an angle of 21.0 degrees. What is the wavelength (in nm)?
- How many dark fringes will be produced on either side of the central maximum if green light (A = 548 nm) is incident on a slit that is 8.00 μm wide? Express your answer using two significant figures. IVE ΑΣΦ m = SWIC ?Coherent light with wavelength 600 nm passes through two very narrow slits and the interference pattern is displayed on a screen 0.80 m from the slits. 13 bright fringes are observed with a spacing of 4.00 cm between the center of the outside fringes. What is the spacing between the two slits? (Give your answer in micrometers.) Ive submitted this question multiple times and it has been incorrect on every occasion. The answer is absolutely not 1.56mm.How many dark fringes will be produced on either side of the central maximum if light (λλ = 699 nm) is incident on a single slit that is 4.84 × 10-6 m wide?
