According to quantum mechanics, people should act like waves, too. The reason we do not exhibit wave properties is that our wavelengths are too small to observe. The reason the wavelengths of people are so small is that when finding the wavelength
A) Planck's constant is small and people masses are much larger than that.
B) Planck's constant is small and people move slowly.
C) Planck's constant is small and the mass of a person isn't very important.
D) Planck's constant is small and people move very fast.

Question

Quizplus · Accepted Answer

According to the de Broglie wavelength equation, the wavelength of a particle is inversely proportional to its mass and directly proportional to Planck's constant. Since people have much larger masses compared to Planck's constant, their wavelengths are too small to observe. Therefore, choice A is correct because Planck's constant is small compared to the mass of a person.
