A student identified the wavelengths of light in an emission spectrum of an element. She wants to calculate the energy associated with each emission line. She has a table of constants and Planck's equation, E=hν. What else does she need to carry out the desired calculations?
A.
the equation relating the speed of light, wavelength, and frequency
B.
the equation relating energy, frequency, and Planck's constant
C.
the equation relating energy and the specific energy level occupied by an electron
D.
the equation relating the change in energy and the two energy levels involved in the electron transition
