[QUOTE="limany, post: 3583897, member: 366127"] [h2]Homework Statement [/h2] estimate light, eletron, neutron beams energy to use 'order - of - magnitude' [eV] [h2]Homework Equations[/h2] E = hv [h2]The Attempt at a Solution[/h2] E = hv where h is Plancks constant and v is frequency and E is energy 6573 angstroms = 6.573 e-7 m = wavelength (λ) First we must use: v = c/λ where c is the speed of light v = (3.00 e8 m/s)/(6.573 e-7 m) = 4.564e14/s E = (6.63 e-34 J x s)(4.564 e14/s) = 3.026 e-19 J I don't know how can i solve it how can i calculate el, neu?
