Got it! Thanks so much for the help. I finally figured out what I was doing wrong. The difference is 87. I was forgetting to multiply the results by 1.00029 for the cell. Once I did that I got 300,087 for number of wavelengths through the cell versus 300,000 for the number of wavelengths through...

I'm still confused. :(

Here's my problem: One of the arms of Michelson interferometer without the compensator consists of a cell 7.5 cm long. How many fringes would be observed shifting if all the air were evacuated from the cell? Use nvac= 1, nair= 1.00029 and the source wavelength 5,000 Angstoms (1 Angstrom =...

Thanks for all the help. I just realized when I was doing my math I was making the same bone-head mistake over and over again. Must get more sleep to avoid stupid mistakes!

I got that equation from my book and I've tried rearranging it several times and I still get the same answer. What am I missing? 1/do + 1/di = 1/F M= - di/do and since M = -2 I get di = 2do Then I plug that into the equation and still get .12 :(

So then am I only off because of the negative sign? So the answer would be .12 m

If a spherical mirror has a radius of curvature of .24 m and and object is placed in front of it and magnified to twice its size: is the mirror concave, convex, or either? And what is the object's distance? I determined that the mirror was concave, because the question said that the image was...

Does manipulating the controls of an oscilloscope change the characteristics of the input signal being evaluated? Can someone please explain this to me? Thank you.

I think I have a mental block on this, but here's what I've done based on what you said... For the straight wire: B = μ0*I1/2*pi*d I plugged everything in and calculated B = 4 x 10-6 Then do I use that B in the second equation: B= μ0*N*I2/2*r to solve for I? I don't get a round...

So, the field at the center of the circular loop due to the straight wire is zero when the current is 3 AMPs. How do I go from there to determine the current at I(1) - the loop? I guess I don't understand what you mean by equating them.

A circular wire loop with a diameter of 0.2m and a long, straight wire carry currents, I(1) AMP and I(2) AMP, respectively. Both wires are located in the plane of the page, and the distance between the long wire and the center of the circle is 0.15m. What is the magnitude of I(1) if the...
