NSM12C PAL Take-‐Home Quantum Mechanics Name: __________________________ Having read the material in chapter 7 you should by now be familiar with the following equations and constants. Prior to using them in calculations, it is important to understand the meaning and units of each. Chapter 7 Key Equations: E = h⋅ν h h λ= Δx ⋅ mΔv ≥ h⋅c (1) ν ⋅λ = c E= 4 π (3) m ⋅ v (4) λ (2) h⋅ c ⎛ 1 1 ⎞ 1 ΔEn = −2.18 × 10−18 J× ⎜ 2 − 2 ⎟ λphoton = Bohr Atom En = −2.18 × 10−18 J × 2 ΔE n ⎝ nfin nin ⎠ Key Constants: c = 2.998 × 108 m/s h = 6.626 × 10 -‐34 J⋅s RH = 2.18 × 10 -‐18 J 1.
