Lote Une A Two Slit Interference Experiment To Determine The Unknown Wavelength Of A Laser Light Source As Shown In Fig 1 (34.99 KiB) Viewed 31 times

Lote une a two-slit interference experiment to determine the unknown wavelength of a laser light source, as shown in Figure 1). With the sits 0-200 mm apart and screen at a distance of 1.00 m, the third bright and out from the central bright and is found to be 9.49 mm from the center of the screen (0) What is the wavelength of the light? (b) How far apart would the slits have to be so that the fourth minimum (dark band) would occur at 9.49 mm from the center of the screen? SOLUTION SET UP AND SOLVE Part (a): Withm=3 (9.5x10(2.000m) mil 13)(1.00 6.33 x 10 m.633 nm Part (b): For destructive interference, and therefore a minimum moves the first minimum m1 the second m2 the third, and m = 3 the fourth. Thus, ( mAR (3+6.33410 (100) d 0.49810 2.33 10m 0.233 mm REFLECT This wavelength corresponds to the red light from a hellum-neon laser Part A- Practice Problem: Figure 1 of 1 if a laser pointer with 616 nm is used, where would the screen have to be placed in order to find the third fringe 9.49 mm from the centralinge?
