13. The condition for a maximum in the twoslit interference pattern is
d
sin
θ
=
mλ
,whe
re
d
is the slit
separation,
λ
is the wavelength,
m
is an integer, and
θ
is the angle made by the interfering rays with
the forward direction. If
θ
is small, sin
θ
may be approximated by
θ
in radians. Then,
θ
=
mλ/d
