... a point in space, whereas a wave must be spread out over a region of space that at least is larger than its wavelength. The standard answer is that light is either wave-like or particle-like depending on what measurements we choose to make on it. For example, if I tune my AM receiver to 550 kHz to l ...

... We can plug in the Coulomb force law for F, and solve the equation for a given initial value of r. If rinitial is 10 Å (10-10 m), a typical distance for an H atom, the calculation indicates that r = 0 at t = _______ sec! This predicts that the electron should plummet into the nucleus in ____________ ...
