Quantum Physics is the branch of physics that deals with the behavior of particles on atomic and subatomic scales. It introduces concepts such as quantization of energy, wave-particle duality, uncertainty principle, and quantum entanglement.
Particles like electrons exhibit both wave and particle properties.
It is impossible to know both the position and momentum of a particle with complete certainty.
A particle can exist in multiple states simultaneously until measured.
Particles can pass through potential barriers that would be impossible in classical physics.
Energy of a photon is proportional to its frequency. (Planck's relation)
de Broglie wavelength: Wave nature of particles where h is Planck’s constant and p is momentum.
Heisenberg Uncertainty Principle: Limitation on simultaneous measurement of position and momentum.
The square of the wave function gives the probability of finding a particle.
Solution: E = hf = 6.63×10⁻³⁴ × 6×10¹⁴ = 3.978×10⁻¹⁹ J
Solution: λ = h/p = 6.63×10⁻³⁴ / 1 = 6.63×10⁻³⁴ m
Solution: Δp ≥ ℏ / 2Δx = (1.055×10⁻³⁴) / (2×10⁻¹⁰) = 5.28×10⁻²⁵ kg·m/s
