Under the right circumstances, a photon of high enough energy can give rise to an electron-positron pair. What minimum energy photon is required?
This question relates to the practicality of searching for intelligent life in other solar systems by detecting their radio broadcasts (or aliens find us from ours). The closest stars are 4 light years away from us. How far away must you be from a 881 kHz radio station with power 50.0 kW for there to be only one photon per second per square meter? Assume that the photons spread out spherically.

- At what velocity does a proton have a 6.0-fm wavelength (about the size of a nucleus)? Give your answer in units of c.arrow_forwardA) What is the approximate wavelength emitted from helium represented by the bright yellow emission line below? What is it's frequency in HZ and energy in eV? (1 eV= 1.6 x 10-19 joules). B) If the excited helium electron that emits a yellow photon in this line starts with a potential energy of 8 eV, what is the potential energy of the electron afterwards? Assume that the emission of a yellow photon is allowed by the laws of quantum mechanics. Also don't worry about the other electron.arrow_forwardYou have a fluorescent molecule that has an excitation wavelength of 320nm and an emission wavelength of 550nm. (a) What would be the wavelength of photons you would use to excite this fluorophore using two- photon microscopy? (b) Suppose that, unfortunately, the tissue you want to image will absorb any light that has more energy than 3.5*1019J. Will two-photon microscopy still work? What's the wavelength of the highest energy of light that will penetrate the tissue? (c) To what part of the EM spectrum do these photons belong? (Give answers for one excitation with one photon, two photons, and the emission wavelength.)arrow_forward
- Please show a complete, detailed solution for this problem. Thank you!arrow_forwardA buckyball consists of 60 carbon atoms arranged in the form of a hollow ball. Say that we illuminate a free, initially non-rotating buckyball with visible light with the intensity of sunlight (1000 W / m2) whose photons all have their spins aligned with their direction of motion. About how long after the illumination begins will the buckyball (on the average) be spinning a million times per second, assuming it absorbs all the light falling on it? (Hints: look in a periodic table to see the mass of a mole of carbon atoms, and remember that Avogadro's number is 6.02 x 1023. Estimate the average wavelength of visible light. You should find that you don't need to know the buckyball's radius.)arrow_forwardThe Theta nuc solution is incorrect. "Determine the angle between the momentum of the electron and the momentum of the second (recoiling) nucleus." Please rework it as it cannot be 125 degrees. (A tad frustrating I have to spend another of my limited 30 questions on this)arrow_forward
- For Q6 through Q8, use the following information. A positronium atom is formed from an electron and a positron, the positron being a particle like an electron, with essentially the same mass, but with a positive charge. Presume that the model for a positronium atom is otherwise like the hydrogen atom, but with this different mass for the positively charged particle. The different reduced mass of this system will lead to different "Rydberg" and "Bohr radius" values. Give your answer to three significant figures, using scientific notation (i.e. 1.23e-3). What will be the "Rydberg" (and hence the magnitude of the "binding" energy), in eV, of this positronium particle?arrow_forwardSuppose we produce X-rays not by smashing electrons into targets, but by smashing protons, which are far more massive. If the same accelerating potential difference is used for both, how would the cutoff wavelengths of the two X-rays compare? Explain. (Hint: the accelerating potential difference causes electrical potential energy to be converted into kinetic energy, that is, Δ? = −Δ? where electrical potential energy ? = ?V and V is the electrical potential difference the charged particles travel through.arrow_forwardThis question relates to the practicality of searching for intelligent life in other solar systems by detecting their radio broadcasts (or aliens find us from ours).
