    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.

    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.

    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...

    Amplitude of an electron

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

    Amplitude of an electron

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

    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...

    Amplitude of an electron

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

    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.

    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...

    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.

    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?

    Higher order Calc project

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

    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.
