15. The angular positions of the maxima of a two-slit interference pattern are given by d sin θ = , where

d is the slit separation, λ is the wavelength, and m is an integer. If θ is small, sin θ may be approximated
by θ in radians. Then, θ = mλ/d to good approximation. The angular separation of two adjacent
maxima is ∆θ = λ/d. Let λ



be the wavelength for which the angular separation is 10.0% greater. Then,

1.10λ/d = λ



/d or λ



= 1.10λ = 1.10(589 nm) = 648 nm.
