Unformatted text preview: ts 0.2 mm apart. Approximately how far apart are the bright interference lines on a screen 5 m away from the double slits? Solution: The separation between bright interference lines: L L y = ym +1 ym = [( m + 1) m] = d d 9 L (632.8 10 m)(5m) y= = = 1.58cm d 0.2 10 3 m 37.4 Intensity Distribution of the double-slit interference pattern Electric field intensities at P: Path difference of two waves: = r2 - r1 = d sin E1 = E0 sin t Condition for constructive interference: = d sin = m (m = 0, ±1, ±2, …) Condition for destructive interference: = d sin = ( m + 1 ) (m = 0, ±1, ±2...
