QUANTUM TUNNELLING

Quantum Tunnelling is when a tiny particle can pass through a barrier that would normally be impossible to cross,like a ball passing through a wall. In the quantum world this is possible as particles show wave particle duality,so they can sometimes "tunnel" through the barrier.

Explanation of Quantum tunnelling in detail and in a more scientific way- It is a phenomenon in which particles pass through a potential energy barrier that would be classically impossible to overcome. This occurs as the wave nature present in the particles allows them to tunnel.

In classical world, the behaviour of particles can be described by Newton's laws of motion. However, in the quantum world, particles are described by the laws of quantum mechanics. Wavefunction of particle describes the probability of finding a particle in a region.

When a particle encounters a potential energy barrier, the probability of the particle passing through the barrier is low.However,in the quantum world,the wavefunction of the particle extends beyond the barrier, allowing a small probability of the particle "tunnelling" through it

The probability of quantum tunnelling depends on the height and width of the potential energy barrier, as well as the energy of the particle. The higher the barrier and the lower the energy of the particle, the lower the probability of tunnelling.

Applications of Quantum tunnelling- 1. Nuclear fusion 2. Scanning tunnelling microscopy. 3. Quantum computing 4. Alpha decay

Overall, quantum tunnelling is a fascinating phenomenon that highlights the strange and counterintuitive behaviour of particles in the quantum world.
