Suppose you observe nineteen bright fringes in the central maximum of a double-slit interference pattern.If you know that the separation of the slits d = 0.06 mm,you can conclude that the width of each slit is
A)0.048 mm
B)0.024 mm
C)0.003 mm
D)0.006 mm
E)0.012 mm

Question

Quizplus · Accepted Answer

The width of each slit can be determined using the formula for the angular width of the central maximum in a double-slit interference pattern. The angular width is approximately equal to the wavelength divided by the slit separation. Given that there are nineteen bright fringes, the width of each slit is approximately 0.006 mm.
