Is it something to do with the intensity of the light? i.e the intensity of the maxima directly opposite the 5th slit would be the highest? I'm afraid I don't understand this topic very well.
Hi
The correct answer is 1.44 x 10^-3 radians, which is exactly 4 times the value of my answer, this is the same for the sines. However I do not understand why exactly it is the correct answer. I know the fact that there is 8 slits makes a difference, whereas my method does not include that...
Homework Statement
A system of 8 slits, each separated from its neighbour by 0.05 mm, is illuminated with light of
wavelength 576 nm. Using phasor analysis, evaluate at what angle on a distant screen there is the first
minimum in intensity.

Hi guys
I've been having some trouble plotting the p(x) and d(xy) atomic orbitals on Matlab.
I have been given that p(x) = x*e^-(x^2 + y^2 + z^2)^0.5
and d(xy) = x*y*e^-(x^2 + y^2 x^2)^0.5
Now I want to plot these orbitals on MATLAB using mesh or the surf command and then plot the...
Force = momentum/time, so the force carried by the jet is equal to pAu^2 which was the answer to one of the first questions, converting A into metres squared this would give force of 0.392N, I calculated max friction to be 0.147N and so the force is sufficient to dislodge the target, hopefully...
Ok, I have attempted the next part, I went about it using a standard projectile motion method and ended up with ucos(theta) = root(5g) and then ended up with u = root(10g) and theta = 45 degrees
Using the value of u I get the force on the piston to be 1.96 x 10^(-5) N which seems pretty small...
Ok, so the volume of water ejected per unit time = area x speed = Au
Volume of water displaced by piston per unit time = Sv (where v is the speed of the piston)
Therefore v = (A x u)/S
Then when I sub that into the power equation I get the correct answer.
Thanks!
Distance/time = speed , If I use u as the speed of the piston I get power(piston) = F x u and use S instead of A for the power transported by the jet I get the correct answer after equating the two. However how would I know that the speed of the piston is u? And I don't see how they involved S?
