State four postulates of plank's quantum theory?

1. Energy is quantized, meaning it can only exist in discrete, specific amounts called quanta.
2. The energy of a photon is directly proportional to its frequency, as given by the equation E = hf, where E is energy, h is Planck's constant, and f is frequency.
3. Electrons in an atom can only occupy certain allowed energy levels, and they can move between these levels by absorbing or emitting photons of specific energies.
4. The probability of finding a particle in a certain position or having a certain momentum is described by a wave function, which can be used to calculate the likelihood of different outcomes in quantum mechanics.

1. Energy Quantization: Energy can only exist in discrete, quantized amounts called quanta, or photons.
2. Wave-Particle Duality: Light and matter have both wave-like and particle-like properties, known as the wave-particle duality of nature.
3. Photon Energy proportional to Frequency: The energy of a photon is directly proportional to its frequency, given by the equation E = hf, where E is the photon energy, h is Planck's constant, and f is the frequency.
4. Conservation of Energy: The total energy of a closed system remains constant, and can only be transferred or converted into different forms, but cannot be created or destroyed.
