Homework #10 (749508) Current Score: 0 out of 100 Description Homework on quantum physics and radioactivity Instructions Answer all the questions as best you can. 1. Hewitt10 32.E.001. [481697] 0/5 points Consider photons emitted from an ultraviolet lamp a TV transmitter. (a) Which is the greater wavelength? ultraviolet lamp TV transmitter (b) Which is the greater energy? ultraviolet lamp TV transmitter (c) Which is the greater frequency? ultraviolet lamp TV transmitter (d) Which is the greater momentum? ultraviolet lamp TV transmitter 2. Hewitt10 32.E.002. [481702] 0/5 points Which color light comes from a greater energy transition, red or blue? blue red 3. Hewitt10 32.P.001. [481739] 0/5 points The higher the energy level occupied by an electron in the hydrogen atom, the larger the atom. The diameter of the atom is proportional to n 2 , where n = 1 labels the lowest, or "ground" state, n = 2 is the second state, n = 3 is the third state, and so on. If the atom's diameter is 1 10 -10 m in its lowest energy state, what is its diameter in state number 45 ? 2.03e-07 m How many unexcited atoms could be fit within this one giant atom? 8.30e+09 4. Hewitt10 31.E.013. [481607] 0/5 points In the photoelectric effect, does brightness or frequency determine the kinetic energy of the ejected electrons? frequency brightness
