- Help Mearrow_forwardb. A photon of wavelength (Z + 22) × 10-12 m is collided with an electron from a carbon block and the scattered photon is detected at (Z + 75)° to the incident beam. Find the energy absorbed by the recoil electron.arrow_forwardIn developing night-vision equipment, you need to measure the work function for a metal surface, so you perform a photoelectric-effect experiment. You measure the stopping potential V0 as a function of the wavelength l of the light that is incident on the surface. You get the results in the table. In your analysis, you use c = 2.998 x 108m/s and e = 1.602 x 10-19 C, which are values obtained in other experiments. (a) Select a way to plot your results so that the data points fall close to a straight line. Using that plot, find the slope and y-intercept of the best-fit straight line to the data. (b) Use the results of part (a) to calculate Planck’s constant h (as a test of your data) and the work function (in eV) of the surface. (c) What is the longest wavelength of light that will produce photoelectrons from this surface? (d) What wavelength of light is required to produce photoelectrons with kinetic energy 10.0 eV?arrow_forward
- A hydrogen atom on the surface of the sun radiates a photon with wavelength 1800 nm. The sun has a radius, Tsun = 6.96 × 108 m, and a mass, Msun = 1.99 × 10³⁰ kg. (a) Calculate the change in wavelength when the photon is observed a long way - effectively at an infinite distance from the sun (or any other massive object). (b) How fast and in what direction would the observer have to move in order to cancel this change in wavelength?arrow_forwardAn apparent limit on the temperature achievable by laser cooling is reached when an atom's recoil energy from absorbing or emitting a single photon is comparable to its total kinetic energy. Make a rough estimate of this limiting temperature for rubidium atoms that are cooled using laser light with a wavelength of 780 nm.arrow_forwardYou want to use a microscope to study the structure of a mitochondrion about 1.00 um in size. To be able to observe small details within the mitochondrion, you want to use a wavelength of 0.0500 nm. If your microscope uses light of this wavelength, what is the momentum p of a photon? p = kg-m/s If your microscope uses light of this wavelength, what is the energy E of a photon? E = If instead your microscope uses electrons of this de Broglie wavelength, what is the momentum p. of an electron? Pe = kg-m/s If instead your microscope uses electrons of this de Broglie wavelength, what is the velocity v of an electron? v = m/s If instead your microscope uses electrons of this de Broglie wavelength, what is the kinetic energy K of an electron? K = What advantage do your calculations suggest electrons have compared to photons? O An electron's charge allows it to attach to observed particles, whereas a photon's electric neutrality prevents it from moving close enough to the observed particles…arrow_forward
