Recall that the energy of a photon (E) is given by:
h = Planck’s constant (6.626 × 10–34 J • s)
v = frequency (in s–1)
Also, recall that the frequency (v) and wavelength (λ) are related:
c = speed of light (3.0 × 108 m/s)
Calculate the energy of the violet light emitted by a hydrogen atom with a wavelength of 410.1 nm.
A. 4.85x10-19 J
