Rearranging, we get v = c / wavelength. The unit for frequency is 1/sec or sec^-1. According to Planck's equation, E = hv where h = Planck's constant = 6.626 x 10^-34 Joules-second = 6.626 x 10^-34 J-s Since you've already computed for v, then you can solve for E. E = (6.626 x 10^-34 J-s) x (5.41-10^14 / s) = 3.58 x 10^-19 J The unit of energy is Joules (J). =)

Your answer is right since wavelength = c/v. Rearranging, we get v = c / wavelength. The unit for frequency is 1/sec or sec^-1.

According to Planck’s equation, E = hv
where h = Planck’s constant = 6.626 x 10^-34 Joules-second = 6.626 x 10^-34 J-s

Since you’ve already computed for v, then you can solve for E.
E = (6.626 x 10^-34 J-s) x (5.41-10^14 / s) = 3.58 x 10^-19 J

The unit of energy is Joules (J).
