the screen?
a) 300 nm
b) 600 nm
c) 900 nm
d) 1200 nm
There may be more than one choice! Explain your answer clearly!

    when the two waves interfere with eachother to make a dark spot the periodic difference of the two waves is π . the wave length for 2π is 600nm

    . ie. for π difference it is 300nm
