Matter Waves - Double Slit Interference Previously we learned the wave behaviors of light - the single-slit diffraction, and the double-slit interference. In this problem, you will explore the wave behaviors of matter (particles). Double Slit Screen Interference y=Ltane 0 L bright fringes: sine Dark fringes above central sin 8 = (m m-0, 11, 12(constructive) (destructive).

Velma's rocket ship is moving away from Mort at a speed of 0.75c. Mort fires a laser beam toward her spaceship, observing the tip of the laser beam to move away from him at speed c. Velma observes this laser beam to move past her at a speed of 1.75c. 1.25c. 0.25c. 0.75c. None of the above. We know that light is quantized because, in the double slit experiment with light, when one slit is closed, no interference pattern shows...

E (t) = Eo cos (kz-wt) Where k is the wave-number and w is the angular frequency of the wave. Now some scientist tells you that a distant star has been observed to be green in color, with an observed frequency of fobserved 550 THz (terahertz, 1012). She also says that from other factors, it is known that the star should be emitting light with wavelength factual-1800 THz somewhere in the UV spectrum. They ask you to find two things...

Learning Goal: To understand de Broglie waves and the calculation of wave properties. In 1924, Louis de Broglie postulated that particles such as electrons and protons might exhibit wavelike properties. His thinking was guided by the notion that light has both wave and particle characteristics, so he postulated that particles such as electrons and protons would obey the same wavelength-momentum relation as that obeyed by light: λ=h/p, where λ is the wavelength, p the momentum, and h Planck's constant. Part...

3. The Milky Way's Dark Matter Halo The Milky Way's rotation curve is approximately a constant, v(r) ~220 km/s, for 5 20 kpc, This constant circular velocity cannot be explained by the observed distribution of luminous mass Instead, we propose that the Milky Way is embedded in a roughly spherical dark matter halo. (a) Calculate M(r), the enclosed mass of the spherical dark matter halo as a function of r in the range 5< T < 20 kpc, assuming the...
