Grade 10Wave Motion
The vibration frequencies of atoms in solids at normal temperatures are of the order of 10.0 THz. Imagine the atoms to be connected to one another by springs. Suppose that a single silver atom vibrates with this frequency and that all the other atoms are at rest. Compute the effective force constant. One mole of silver has a mass of 108 g and contains 6.02 × 1023 atoms.
