When an electron makes a transition from the n=3 to the n=2 hydrogen

atom bohr orbit, the energy difference between these two orbits

(3.0x10^-19 J) is given off in a photon of light. The relationship
...
between the energy of a photon and its wavelength is given by

E=hc/wavelength, where E is the energy of the photon J, h is planck’s

constant (6.626x10^-34 J x s), and c is the speed of light (3.00x10^8 m/s)

Find the wavelength of light emitted by hydrogen atoms when an electron makes this transition.
