Question

An alpha particle moving with an initial velocity $\left(uj\right)$enters a region of uniform magnetic field $B=Bk$. the de-Broglie wavelength of the alpha particle.

• A. Increases to a higher constant value
• B. Decreases to a lower constant value
• C. Increases and decreases periodically
• D. Remains constant

Answer 1

The correct option is D Remains constant

de-Broglie wave length remains constant.

$\therefore$ Option $D$ is correct.
