A) 1/4
B) 1/16
C) 16
D) 4

Question

Quizplus · Accepted Answer

According to de Broglie's equation, λ = h/p, where λ is wavelength, h is Planck's constant, and p is momentum. As momentum (p) is inversely proportional to wavelength (λ), if momentum is quartered (divided by 4), then wavelength will be quadrupled (multiplied by 4). Therefore, the corresponding wavelength changes by a factor of 4. The answer is D.
