# Green light has a wavelength of 5.010^2 nm. what is the energy in joules of one photon of green light [Solved] E=h*nu
c=nu*lambda

Frequency = speed of light/wavelength
F = 310^8/510^-7 = 610^14 Hz

Energy = Planks Constant x frequency
E= 6.6310^-34 * 610^14 = 3.97810^-19 which is roughly equal to 410^-19 J for the energy of 1 photon of green light.

3.010^8 m/s = (5.010^-7 m)v

Hope this helps!

E=h*nu
c=nu*lambda

h is Plancks constant.

where h is plancks constant(m2 kg/s2), nu is frequency(1/m), lambda is wavelength (m), and E (J). thats for one photon, so then just multiply by avogadros #.

This would give you the answer for one photon, and multiplying that by 6.0210^23 would give you the answer for one mole.

Once you solved for v, you would plug that into the equation E=hv, and solve for E. (By the way, the units for v is per seconds, or s^-1.)

This would give you the answer for one photon, and multiplying that by 6.0210^23 would give you the answer for one mole.

3.010^8 m/s = (5.010^-7 m)v

E=h*nu
c=nu*lambda

E=h*nu
c=nu*lambda

First you would plug in 5.0 x 10^-7 m into the first equation and solve for v, the frequency.
