You would like to observe an E. coli bacterium that is 1.95 um long. Because diffraction blurs an image, you would like to minimize the effects of diffraction by using a wavelength no larger than the object you are observing. For this problem, assume the wavelength is equal to the length of the bacterium. What is the energy of a photon with this wavelength? energy of photon: J What is the energy of an electron with a de Broglie wavelength...

Second part of part c) please! The bit that asks about the
particle travelling 75m in the laboratory before it decays.
Determine its lifetime in the lab frame and then in its rest
frame.
-+160% are s two postulates of Special Relativity 4 marks) b) Calculate the de Broglie wavelength of an eleetron moving at a speed of 0.70c. The rest mass of an electron is 9.11 x 10-31 kg. 5 mar c) An elementary particle has a total energy...
QUESTION 1 If you wanted to double the momentum of a photon you would 1. double its velocity. 2. double its mass. 3. double either its mass or its velocity. 4. double its wavelength. 5. decrease its wavelength by a factor of two. In the photoelectric effect, if we double the intensity of the beam of light which has a frequency below the cutoff frequency, the number of electrons ejected per second will 1. double. 2. go up by factor...
