There is a difference between classical and quantum particle, hence their mechanics also differ.
For example, the size of a classical particle is far larger than tenderise to minus nine meters.
But when we talk about a quantum particle, it's near or less then enriched to minus nine meters.
So we can clearly see the mechanics also would change in a lot of aspects.
Let's take an example of a classical particle, let's say a football at position X is moving with a
velocity V now with the Newtonian formulae, we can predict the future position of the football.
So the nature of classical particle is deterministic in nature.
In the quantum world, a particle is represented as.
A group of views that can interfere constructively or destructively, let's see how can we interfere
constructively and destructively and what is going to be the impact on the final of.
As you can see over here on the left hand side, there are two waves, which is basically creating a
bigger view because they are interfering constructively while on the right hand side, you see the two
views are interfering destructively.
Hence the amplitude is levelled out.
Let's take an example in the classical world, if a bus is moving with Velocity V, then the bus driver
is also moving with the same velocity and the kids are also moving with the same velocity.
Now, let's take an example in the quantum world.
Let's say a rugby team is performing the Hucker dance.
Now, the whole team would move with a certain velocity is called as group velocity, and the individual
members that forms a group has a fierce velocity.
