estimate light, eletron, neutron beams energy to use 'order - of - magnitude'
E = hv
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?
