Actually, the equation for the constructive interference is 2t=(m+1/2)*wavelength, not really m-1/2. But I guess it could be right. OK, I will try.

So I assume n=1.00029 roughly equal to 1. so the equation simplifies to 2t= m*wavelength. There will be a constructive interference as the ray is reflected off of the glass into the air since air acts as a sliding ring.

Homework Statement A pair of very flat glass plates, 7.41 cm long, touch at one end and are separated at the other end by a small piece of 44 gauge copper wire, 5.08×10−5 m in diameter. An air wedge is formed between the glass plates by this supporting wire. Light of wavelength 631 nm...

I apologize for what I said since I finally got the answer.

OK I got it. The amplitude must be 3.448e-7m. Vmax=-A*2pi*f

Bohr radius is 5.29e-11m by the way.

Fortunately it does help me.

Electrons have dual nature of wave and also of particle. Did you study anything about electrons and current and the fact that it moves in a zigzagging path? It's a wave as well. But if you say so, which equation are you talking about and if you know it why not put it on your pose unless you're...

I supposed I did but you didn't explain why there's no distance dependence.

Asin(2pi*x/lambda-2pi*f*t)=y as a function of x and t. and you're not helping me yet.

Homework Statement In a typical household current, the electrons in the wire may have a drift speed of 1.3×10−4 m/s. Actual household current is not a direct current, but instead is an alternating (oscillating) current. (If you have ever received an electric shock from an outlet, you have...

http://www.icp.uni-stuttgart.de/Jahresberichte/01/node2.html provides a good detailed explanation of the applications. It doesn't really look too hard though.

Is it possible to interpret fractional calculus in a physical sense like the first derivative is the rate of change, but if it's fractional, what does that represent?

Hmm. Fractional calculus sounds pretty cool. But any cool applications associated with that?

I was wondering if there are any topics for calculus based or advanced high school math project that I can devote my whole semester to at school.
