Optics Homework (11th grade)

  1. Jun 6, 2014 #1
    So I got a warning for just posting questions so I'll do as best as I can to try and put effort lol

    1. The problem statement, all variables and given/known data

    A Young's interference experiment is performed with monochromatic light. The separation between the slits, d, is .50 mm, and the interference
    pattern on a screen L = 3.3 m away shows the first maximum y1 = 3.4 mm from the center of the pattern. What is the wavelength?


    GIVEN DATA

    d=.50mm

    L=3.3m

    y1= 3.4mm


    2. Relevant equations

    Yn=(nλL)/d

    3. The attempt at a solution

    I need to know if I'm attempting this right.

    I started off by plugging in y1=3.4mm, L=3.3m and d=.50mm

    Pretty simple.
    3.4=(nλ3.3)/.5

    1.7=(nλ3.3)

    .5151.....=λ

    ???

    Am I right by plugging in 1 for n???

    Quoting from the text you provided "first maximum y1 = 3.4 mm".

    So..... Am I right?

    Do you need to ask? the formula given is for yn, you were given y1, what do you think n is?

    Oh I just needed to make sure. So yn(subscript), whatever is in the subscript is just n?
