CHEM 130 Lecture 5: CHEM LECT 5
Document Summary
Clicker: blue leds produce light with a wavelength of 475 nm. Clicker: it takes 208. 4 kj of energy to remove 1 mole of electrons from an atom on the surface of rubidium metal. How much energy does it take to remove a single electron from an atom on the surface of solid rubidium and what is the maximum wavelength of light capable of doing this? h= 6. 626 x1034 js. Note: maximum because a lower wavelength lower than that would be higher energy. A wavelength higher than that would be lower energy. Clicker: what is the kinetic energy of the electron emitted when a photon with frequency, = Hz is incident upon a metal with 0 = 7. 00 10. Clicker: neutron diffraction is used in determining the structures of molecules. Calculate the de broglie wavelength of a neutron moving at 1. 00% of the speed of light.
