According to de Broglie,as the momentum of a moving particle is tripled,the corresponding wavelength changes by what factor?
A)1/9
B)1/3
C)3
D)9

Question

Quizplus · Accepted Answer

According to de Broglie's equation, λ = h/p, where λ is the wavelength, h is the Planck's constant, and p is the momentum of the particle. If the momentum is tripled, then the wavelength will be 1/3 of its original value because the wavelength is inversely proportional to momentum. Therefore, the corresponding wavelength changes by a factor of 1/3, which is option B.
