Bullets of mass 3.99 grams (g) are fired in parallel paths with speeds of 195 m/s through a hole 3.06 mm in diameter. How far from the hole must you be to detect a 1.69 cm-diameter spread in the beam of bullets?

By Thomson's time, it was known that excited atoms emit light waves of only certain frequencies. In his model, the frequency of emitted light is the same as the oscillation frequency of the electron or electrons in the atom. What would the radius of a Thomson-model atom have to be for it to produce red light of frequency 4.55×1014 HzHz ? (see Appendix FF from the textbook for data about the electron)

An electron is moving at 6.0 x 10^6 m/s. A photon of what wavelength would have the same (relativistic) momentum as the electron?

What is the velocity (in m/s) of a 0.430 kg billiard ball if its wavelength is 7.70 cm (large enough for it to interfere with other billiard balls)?

X-rays are scattered from a target at an angle of 54.9° with respect to the direction of the incident beam. What is the wavelength shift (in m) of the scattered x-rays?  What If? For what scattering angle (in degrees) will the wavelength shift of x-rays be exactly double that found in part (a)?

During a certain experiment, the de Broglie wavelength of an electron is 610 nm = 6.1 x 10- m, which is the same as the wavelength of orange light. How fast (in m/s) is the electron moving? m/s

An x-ray is modeled by the equation E= (1000V/m)sin(kx - 8.96 *1018t) What is the wavenumber, k, in m-1, of this x-ray?
