A crystal has regularly spaced atoms that can act like a diffraction grating (which has many evenly
spaced slits). Diffraction patterns form when the wavelength of a photon is similar in size to the
spacing between atoms. Consider a crystal where the atomic spacing is 0.23 nm, and a photon of
wavelength equal to this spacing.
What part of the electromagnetic spectrum is such a photon?
O infrared
Ovisible light
O ultraviolet
Ox-ray
gamma ray
What is the momentum of this photon?
Pph =
kg-m/s
Note that you will need to use exponential notation for your answer. Express it using "E": 1.23
x1024 is entered as 1.23E24.
Particles such as electrons can act like waves just as photons do. In fact, they can be diffracted in
just the same way by a crystal. What momentum would an electron have if its wavelength equals
that of the photon (per the previous answer)?
kg-m/s (Use exponential notation as above)
What is the velocity that such an electron would have? For reference, the electron mass is 9.11…
An electron microscope uses magnets to accelerate electrons with negligible initial speed through apotential difference of 50 million volts. Calculate the ratio of the resolution of this electron microscope to theresolution of a microscope that uses visible light with a wavelength of 5.00 × 10−7 m through a circularaperture with an aperture of 5.00 mm.
|In a photoelectric effect experiment, the frequency of photons bombarding the surface is increased until
photoelectrons just start to leave the surface. If this occurs at a frequency of 6.0 x 1014 Hz, what is the work
function of the surface?
