Unformatted text preview: ground ( n = 1) state, (a) does it emit or absorb a photon? (b) Let E 1 be the energy of the ground state and E 2 , the energy of the excited state. What is the frequency of the photon involved in this process in terms of E 1 , E 2 , and h (Plancks Constant)? 4. The DeBroglie Wavelength of a particle (Matter Waves) was said in class to be h/ ( mv ) where h is Plancks Constant, m is the particles mass, and v is the particles speed. (a) What is the DeBroglie wavelength (in meters) of an electron moving at a speed of 10 5 m/s ? (b) What is the DeBroglie wavelength (in meters) of a 3000 kg vehicle moving at 80 kilometers/hour?...
