1. ### Thin Film interference: air wedge

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.
2. ### Thin Film interference: air wedge

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.
3. ### Thin Film interference: air wedge

1. 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...
4. ### Amplitude of an electron

I apologize for what I said since I finally got the answer.
5. ### Amplitude of an electron

OK I got it. The amplitude must be 3.448e-7m. Vmax=-A*2pi*f
6. ### Electron orbital frequency of hydrogen atom if given orbit radius

Bohr radius is 5.29e-11m by the way.
7. ### Amplitude of an electron

Fortunately it does help me.
8. ### Amplitude of an electron

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...
9. ### Amplitude of an electron

I supposed I did but you didn't explain why there's no distance dependence.
10. ### Amplitude of an electron

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

1. 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...
12. ### Higher order Calc project

http://www.icp.uni-stuttgart.de/Jahresberichte/01/node2.html [Broken] provides a good detailed explanation of the applications. It doesn't really look too hard though.
13. ### Higher order Calc project

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?
14. ### Higher order Calc project

Hmm. Fractional calculus sounds pretty cool. But any cool applications associated with that?
15. ### Higher order Calc project

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.
