Question: `qGeneral College Physics and Principles of Physics Problem 24.2: The third-order fringe of 610 nm light created by two narrow slits is observed at 18 deg. How far apart are the slits?
YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution:
m=3 wavelength=610nm=6.1x10^-7m angle=18 degrees d=?
d*sin’theta = m*wavelength
d = (3*6.1x10^-7m)/sin 18
d=5.92 x 10^-6 m
&#Good responses. Let me know if you have questions. &#
