Homework Statement X-rays of wavelength λ are incident on a cubic crystal with spacing d as shown in the figure. The incident angle is fixed at θi degrees. A detector is rotated from perpendicular to the 100 plane (90 degrees (grazing)) until the first maximum is detected at θs degrees due to...

just kidding I plugged it in wrong. Thanks for your help!

okay so it isn't 90, I the angle for the field will be the other angle in that triangle (see sketch), but when I tried it, it too gave me the wrong answer.

is the angle 45 because it will be tangent to the field line? aka there is a 90 degree angle between the two components

so the top wire would be counter clockwise and the bottom would be clockwise. the y component of B for the top wire points up and the y component of B for the bottom points down, don't they cancel?

here you go

So cosθ = adjacent/hypotenus in this case adjacent is R=.1 hypotenuse is from half of the distance d (.011/2 = .0055) so using Pythagoreans theorem, I got Hyp = .10015 m. using that instead I get the same value, i think the cosine isn't the issue.

Homework Statement Two long parallel wires are a center-to-center distance of 1.10 cm apart and carry equal anti-parallel currents of 9.70 A. Find the magnitude of the magnetic field at the point P which is equidistant from the wires. (R = 10.00 cm). (See Attachment for orientation) I = 9.7 A...
