(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

estimate light, eletron, neutron beams energy to use 'order - of - magnitude'

[eV]

2. Relevant equations

E = hv

3. The attempt at a solution

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 dont know how can i solve it

how can i calculate el, neu?
