PLEASE ANSWER the MULTIPLE CHOICE QUESTION. I know you have to look at the other problem to find the answer. I wish I could attach the work for it. I need the answer to the multiple choice question. I have wasted 4 questions now. I keep getting an answer to the story problem. You might need to answer the story problem to answer the multiple choice question. They are connected. Please help.

Consider your work on Problem 25.30. What did
you need to do to find 0 in this problem?
O This is a thin film problem. You don't need 0
O You measure from the center of the screen to
the bright spot, so 0 = 0
O Calculate 0 from the interference equation.
You are given all the other values in the
formula.
O Calculate 0 from trigonometric functions like
sine or tangent.

30. * Two narrow slits are used to produce a double-slit interfer-
ence pattern with monochromatic light. The slits are separated by
0.90 mm, and the interference pattern is projected onto a screen
9.5 m away from the slits. The central bright fringe is at a certain
spot on the screen. Using a ruler with one end placed at the cen-
tral fringe, you move along the ruler passing by two more bright
fringes and find that the third bright fringe is 20 mm away
the central fringe. What is the wavelength of the light?
