X-ray cut-off
λ_min = hc/(eV)
Where: V = volume (m³) / potential difference (V), c = specific heat (J/kg·K) / speed of light, e = electron charge (C) / coefficient of restitution, h = height (m) / Planck constant, λₘᵢₙ = X-ray cut-off
Solved example
Given: V = 7, c = 5, e = 10, h = 4
Find: lamda_min (X-ray cut-off)
- Formula: λₘᵢₙ = c·h/(V·e)
- Substitute the values: λₘᵢₙ = 4·5/(10·7)
- Result: λₘᵢₙ = 0.285714
Answer: lamda_min = 0.285714
