Homework Statement
Light of wavelength 473 nm falls on two
slits spaced 0.389 mm apart.
What is the required distance from the slit
to a screen if the spacing between the first and
second dark fringes is to be 6.71 mm?
Answer in units of m.
Homework Equations
sin\theta= m\lambda/d
x=tan\theta*L
The Attempt at a Solution
\theta = sin-1{2*473e-9m / .389e-3 m} = .139336 degrees
L = 6.71e-3 m / tan .139336 = 2.75919
