Section 1

Question Answer
Converting Energy into Wavelength1) Multiply kJ value by 1,000. 2) Divide by Avogadro's Constant. 3) Divide L by the result.
Planck's PostulateE=hv || E=hc/λ
Balmer Equation1/λ = R[1/(2^2) - 1/(n^2)]
Blamer-Rydberg Equation1/λ = R[1/(m^2) - 1/(n^2)]
Einstein's theoryE = mc^2
de Broglie Equationλ = h/mv
Kinetic Energy Formula(p^2)/(2m) = KE = hf - Φ
Momentum derived from KEp = sqrt[2m[(hc/λ) - Φ]]
de Broglie Wavelength Formulaλ = h/p
