    What Wavelength Does a 100mW Laser Deliver 3.5x10^17 Photons in One Second?

    Homework Statement At what wavelength does a 100mW laser deliver 3.5 x 1017 photons in one second? h (plancks) = 6.626x 10^-34 c = 3 x 10^8 Homework Equations E = hf ==> E = hc / n (wavelength) ==> n = hc / E Power = Energy / Time The Attempt at a Solution Energy = Power *...

    How Does a Finite Wire Segment Affect Magnetic Field Calculation?

    Homework Statement A long straight wire lies along the z-axis and carries an 8A current in the +z direction. Find the magnetic field (magnitude and direction) produced at x = 0.4m, y = 0, z = .3m by a .7mm segment of wire centered at the origin. Homework Equations B = u(0)I / 2piR...
