Weather radar systems emit radio waves in pulses. For a typical system the frequency used is 3.00 GHz (1 GHz = 109 Hz) and the minimum energy uncertainty of the radio photons is 5.50 x 10-29 J. Find (a) the time duration of each pulse, (b) the length of each pulse, (c) the energy of an average photon, and (d) the minimum frequency uncertainty.

Suppose Fuzzy, a quantum-mechanical duck, lives in a world in which h=2π Js. Fuzzy has a mass of 2.00 kg and is initially known to be within a pond 1.00 m wide. What is the minimum uncertainty in the component of the duck's velocity parallel to the width of the pond?

Lasers can be designed to emit pulses of light less than 30 microns wide in their direction of motion. The momentum of a photon is given by p = h/λ. Estimate the uncertainty in the wavelength of a photon in the pulse, assuming a nominal wavelength of 800nm.

What is the kinetic energy of each electron in a beam of electrons if the beam produces a diffraction pattern of a crystal which is similar to that of a beam of 1.00 eV neutrons? (knowing that electron mass is 9.11*10^-31 kg and neutron mass is 1.67*10^-26 kg). What are the specific equations that are being used in this problem?

In designing an experiment, you want a beam of photons and a beam of electrons with thesame wavelength of 0.281 nm, equal to the separation of the Na and Cl ions in a crystal ofNaCl. Find the energy of the photons and the kinetic energy of the electrons in electrovolts(eV).

The velocity of an electron is known to be 1.000×105 m/s, with an uncertainty of Av = 1.00×102 m/s. (a) What is the minimum uncertainty in the electron's position, Av, in meters? (b) How does this compare to the de Broglie wavelength of the electron? (c) One of your professors (m = 75.0 kg) is pacing at the front of the classroom, and you measure their velocity to an uncertainty of Av = 0.100 m/s. What is the minimum uncertainty in a measurement of their position? (d) How does this compare to the height of your professor?
