The width of the central bright fringe in a diffraction pattern on a screen is identical when either electrons or optical light pass through a single slit. The distance between the screen and the slit is the same in each case and is large compared to the slit width. If the wavelength of the optical light is 589 nm, how fast are the electrons moving? Give your answer in units of m/s, accurate to 2 decimal places.

According to the principles of quantum mechanics, every particle acts like a wave. To demonstrate this, a helium nucleus is shown to exhibit interference as it passes through a double-slit. The helium nucleus has a mass of 6.64 x 10^-27 kg and its speed is 500.0 m/s when is passes through the slits. a. What is the wavelength of the wave associated with the helium nucleus in nanometers? b. If the slits are seperated by 1.00 nm and the distance from the slits to the detector (effectively, the "screen") is 15.0 cm, what is the distance, in centimeters, from the central maximum to the first-order maximum of constructive interference? c.

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…
