Intensity pattern is sketched in nthe figure given above.
Intensity at a point whose angular location θ at the center of slits is given by
begin mathsize 12px style I subscript theta equals 4 I subscript 0 space cos squared open parentheses fraction numerator pi space d space sin space theta over denominator lambda end fraction close parentheses end style
and φ shown in the graph is given by begin mathsize 12px style phi space equals space fraction numerator pi d over denominator lambda end fraction sin theta end style
λ is the wavelength of the light. Refer the figure for d and θ

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
