de Broglie wavelength
λ = h/p = h/mv
Where: h = height (m) / Planck constant, λ = wavelength (m) / decay constant, p = momentum (kg·m/s)
Solved example
Given: h = 7, p = 5
Find: lamda (wavelength (m) / decay constant)
- Formula: λ = h/p
- Substitute the values: λ = 7/5
- Result: λ = 1.4 m
Answer: lamda = 1.4 m
