Question

According to the modern view of quantum mechanics, which objects can act like waves? A) Light, but not electrons or atoms B) Electrons, but not light or atoms C) Light and electrons, but not atoms D) Light, electrons, and atoms 6. E) According to quantum mechanics, nothing really acts like waves

Answer 1

The correct option is 'D': Light, electrons and atoms.

Step-by-step explanation:

According to the basic postulates of quantum mechanics all the moving objects in the universe have a wavelength associated with them which is given by De-Broglie as

`\lambda =(h)/(mv)`

where

h is known as planks constant

m is mass of the object

v is the velocity of the object

Thus we infer that all the moving objects with mass have a wavelength associated with them, since the masses and the speeds of ordinary objects are small in comparision to magnitude of plank's constant thus we cannot observe the wavelengths with naked eyes
