♦ Relevant knowledge
Every object, which ranges in dimensions from an electron as large as an elephant display the properties of particle and wave. The primary property is determined by the wavelength of the object. The electron has the wavelength of around 10-10 m. A plodding elephant has the wavelength of 10-40 meters! The wavelength of the elephant is too tiny to display any wave-like characteristics.
Wavelength is the characteristic of an object’s wave nature. The wavelength of the baseball’s De Broglie is shown by
The mass of a base ball is more than the value for the plank’ constant, so the wavelength is too small. This smaller wavelength makes it difficult to observe wave-like nature.
Therefore, the correct answer is C. The baseball’s wavelength is too small
