The de Broglie wavelength associated with a moving particle is inversely proportional to its: MCQ with Answer and Explanation

The de Broglie wavelength associated with a moving particle is inversely proportional to its:
A. Velocity only
B. Mass only
C. Kinetic energy
D. Momentum
Answer: Option D
Solution (By JKSSB Mock Tests)
Louis de Broglie proposed that matter exhibits wave-like properties. The de Broglie wavelength (lambda) of a particle is given by the formula lambda = h / p, where 'h' is Planck's constant and 'p' is the linear momentum (mass * velocity) of the particle. Therefore, the wavelength is strictly inversely proportional to the momentum of the moving particle.
