Exercise 4
Step 1
1 of 2
Since white light is compound it contains a continuous range of wavelengths so when it passes through two-slit system different colors will have their points of constructive/destructive interference shifted from each other and this will result in decomposition of white light spectrum.

Exercise 5
Step 1
1 of 2
The condition for constructive interference says
$$
mlambda=dsintheta
$$
. Putting in the data from the problem this becomes
$$
mlambda=dsintheta
$$
. Putting in the data from the problem this becomes
$$
lambda=dsin35^circ
$$
which yields for the distance between slits
$$
d=frac{lambda}{sin35^circ} =frac{670times10^{-9}text{ m}}{sin35^circ} =1.17times10^{-6}text{ m}.
$$
