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.

  1. All you need to do is to substitute the numbers in to E = hc/wavelength.
    3 x 10^-19 = 6.626 x 10^-34 x 3 x 10^8/wavelength.
    Solve for wavelength.

  2. the energy from radiation can be used to cause the rupture of chemicals bonds. a minimum energy of 495 kj/mol is required to break the oxygen- oxygen bond in o2. what is the longest wavelength of radiation that possesses the necessary energy to break the bond?
