What is the de Broglie wavelength of a He atom with a kinetic energy of 0.025 eV? What is the de Broglie wavelength of an electron with the same kinetic energy?
Part A What is the speed of an electron with a de Broglie wavelength of 0.17nm ? Express your answer using two significant figures. Part B What is the speed of a proton with a de Broglie wavelength of 0.17nm ? Express your answer using two significant figures.
T/F: A 100 eV electron and a 100 eV proton have equal de Broglie wavelengths. T/F: In a blackbody, the energy of the oscillating atoms is quantized. T/F: The peak of the radiation curve of a blackbody moves toward larger wavelength as its temperature increases. T/F: At any instant in time, it is possible to specify simultaneously the position and the momentum of a particle to arbitrarily high precision. T/F: Light being amplified by stimulated emission of radiation is the...
What is the de Broglie wavelength of a 162 g baseball with a speed of 38.0 m/s ? (in m) What is the speed of a 162 g baseball with a de Broglie wavelength of 0.230 nm ? (in m/s)
What is the photoelectric effect, who discovered it and what is the key to explaining it?
In the photoelectric effect experiment, a beam of light is shining on a metal surface and the electrons are emitted from the metal. One of the three key findings is that a minimum frequency of light is required for emission of electrons. This minimum frequency is found to be 5.5 × 1014 s-1 for an unknown metal. 4 Briefly describe the other two findings and draw a plot fo the KE of emitted electrons against light frequency. (a) (6 marks)...
