E = hν

E = energy = ?

h = Planck's constant = 6.626x10-34 J-sec

ν = frequency = 4.69x1014sec

E = 6.626x10-34 J-sec * 4.69x1014sec = 3.1x10-19 J

Sally S.

thank you I am just wondering why we don't get 3.1*10^-20 and we get to the -19th power because -34 + 14 is 20.

I think if you multiply you get 30E-30 which is 3E-19. Check the math.
