Rydberg Equation for Hydrogen - ️️ Correct-
Speed of Light/Wavelength/Frequency Equation - ️️ Correct-Speed of Light (3 x 10^8)
Energy of a Single Quantum - ️️ Correct-E = hv
v = frequency (c/λ)
h =...
De Broglie Wavelength Equation - ✔️✔️Correct-λ = h/mu
h = Planck's Constant (6.26 x 10^-34)
m = mass (kg)
u = velocity (m/s)
Heisenberg Uncertainty Principle - ✔️✔️Correct-"It is impossible to know exactly both the
velocity and the position of a particle at the same time"
Δx * mΔu ≥ (h/4π)
Δx = uncertainty in position (m)
m = mass (kg)
Δu = uncertainty in velocity (m/s)
h = Planck's Constant (6.26 x 10^-34)
Effective Nuclear Charge (Zeff) - ✔️✔️Correct-Z* = Z - σ
Z = atomic Number
σ = shielding/screening constant
