Question
The de Broglie wavelength of a vehicle moving with velocity v is λ. Its load is changed so that the velocity as well as kinetic energy is doubled. What will be the new de Broglie wavelength?
Options
A.λ
B.2λ
C.4λ
D.λ/2
Solution
$p = mv = \frac{\frac{1}{2}mv^{2}}{\frac{1}{2}v} = \text{ const} \Rightarrow \lambda\text{= Constant}$
