Question

Why does the ball hit by a hockey player not make a wave?

Answer 1

Hint: De-Broglie states that matter has both particle nature and wave nature. This is also called the dual nature of matter. The de-Broglie wavelength is the ratio of Planck constant and momentum of a particle, where mv is the momentum of the particle.

Complete step by step answer:
The formula of de-Broglie wavelength is \[{\text{\lambda = }}\dfrac{{\text{h}}}{{{\text{mv}}}}\], where m and v is mass and velocity of the particle respectively.Form this formula it is clear that the wavelength is inversely proportional with mass of the substance. With increasing the mass of the substance, the wavelength value will decrease and vice-versa. So, it can be said that the formula of de-Broglie wavelength is valid for very small substances like electrons.
In the case of a hockey ball, the size of that ball is so large and also the mass is very large. Due to this reason the hockey ball does not make any wave.

Note:
The distance between two adjacent crests of a wave is called wave length. Wavelength of a wave can be measured in meters, centimeters, or millimeters units of length. The human eye can detect the wavelengths from about 380 to 700 nanometers. In this range the highest wavelength for red light and lowest is for violet. Wavelength of any wave depends upon the energy of that wave. Higher the energy of the wave lower will be the wavelength and vice-versa.
