But where do I get the angle and wavelength from?

Homework Statement In a double-slit experiment, the third order bright fringe is 15 mm from the central fringe. What is the distance of the first (zero-th order) dark fringe from the central maximum? Homework Equations (m+.5)(lambda) = dsin(theta) => dark fringe m(lambda) = dsin(theta) =>...

Wow! >.< I feel so dumb. Thanks so much for the reply! For some reason, though, my teacher never gave me that formula in class. The ones I gave were all I had to work with. I didn't know you could get magnification without object distances and height!

Homework Statement "Find the magnification of the following system: A diverging lens with focal point -9.5 cm is placed 4.35 cm to the right of a converging lens with its own focal point of 13.0 cm. Parallel light enters the converging lens from the left." Homework Equations M = -p/q 1/p + 1/q...

I understand what I did, but I don't know if it's correct?

I mean, just because I think I did it right doesn't mean I did it right and got it right :/ if I went with that form of logic, I don't think I'd be here asking for help and unsure of myself. I probably would've just spouted whatever I thought was logical and stuck with that answer, unaware of...

Ah okay, so 202.5?

Thank you so much for the help! :D I truly appreciate it! Have a good night! For anyone else out there, is 202.547 microfarads the correct final answer?

I meant C2, sorry! I was looking at the diagram and wrote the wrong thing >.< So (1/105.8) + (1/41.1) = 0.0337826961 => 0.0337826961^-1 = 29.60095303 microfarads?

Okie doke. So now do I add that with C4 as if they are in series?

Ah, okay. So C1 + C3 = 10.3 + 95.5 = 105.8 microfarads?

Basically, what I did was: (1/c5) + (1/[c1+c2+c3+c4]) Then let's say the result is x. x^-1 = Ctot. And from that, I got around 241, give or take a few mistypes in the calculator should there be.

Homework Statement Find the capacitance of the circuit if C1 = 10.3, C2 = 41.1, C3 = 95.5, C4 = 299.9, and C5 = 525.7, with all the units being in microfarads. Homework Equations 1/Series Ctotal = 1/c1 + 1/c2 ... Parallel Ctotal = C1 + C2 + ... The Attempt at a Solution I tried to combine all...

thank you for the help!

Ah okay, I think I got it: 9.55 microfarads Thank you!
