Homework Statement
In a double-slit interference experiment, the slits are illuminated with a red laser light at 632 nm. The interference pattern seen on the screen is drawn below:
How would I carefully draw, in the same diagram, the pattern that you would see with a blue laser at 450 nm...
Current---Can someone solve, please?
Homework Statement
Two long straight parallel wires separated by 1.00mm carrying currents in opposite directions with current equaling 10.0A each. Find the magnitude and direction of the magnetic field at Point A which = 0.50mm, Point B = 0.50mm, and...
I honestly do not even know how to get the magnitude without knowing the magnetic field. This one has me very confused. Please help a little further if possible please?
[b]1. I have a wire that is stretched so that the current is coming directly at me, out of the page. It is shown as a dot on the screen or page. The wire is in a uniform horizontal magnetic field shown as horizontal lines. The direction of the magnetic field is not shown in the figure. Choose...
