Hey dear,
◆ Answer-
λ' = λ/√2
● Explanation-
De Broglie's wavelength is related to voltage applied as -
λ = h / p
λ = h / √(2meV)
When V is doubled,
λ' = h / √(2me2V)
λ' = h / √(4meV)
From (1) & (2),
λ' = λ/√2
Therefore, De Broglie's wavelength is λ/√2 when voltage is doubled.
Hope this helps you...
