sources are 6cm apart, and they are in phase. Two paths are drawn from the sources to a point. (The picture is to scale, even if the sources are not 6cm apart on the paper.) (a) If the wavelength of the two sources is 2cm, for each picture, figure out whether the point marks a position of constructive or destructive interference. (b) Repeat if the wavelength is 1cm
For the figures shown below, the two sources are
6cm apart, and they are in phase. Two paths are
drawn from the sources to a point. (The picture is to
scale, even if the sources are not 6cm apart on the
paper.)
(a) If the wavelength of the two sources is 2cm, for
each picture, figure out whether the point marks a
position of constructive or destructive interference.
(b) Repeat if the wavelength is 1cm.

Solved in 2 steps
For the figure shown below, the two sources are
6cm apart, and they are in phase. Two paths are
drawn from the sources to a point. (The picture is to
scale, even if the sources are not 6cm apart on the
paper.)
(a) If the wavelength of the two sources is 2cm, for
the picture, figure out whether the point marks a
position of constructive or destructive interference.
(b) Repeat if the wavelength is 1cm.
What about for the second picture where the lengths are 4.5 and 2.5?
