Study Notes
Wave-Like Behavior of Matter
- Louis de Broglie proposed the concept that matter behaves like a wave.
Experimental Demonstration
- The Davisson-Germer experiment was the first to experimentally demonstrate the wave-like behavior of matter using electrons.
Wavelength of a Particle
- The wavelength associated with a particle with momentum p is given by λ = h/p, where h is the Planck constant.
Prevailing Belief in the 19th Century
- At the end of the 19th century, the prevailing belief was that light is a wave and matter is composed of small, indivisible particles.
Quantization of Thermal Energy
- Max Planck proposed that the thermal energy of oscillating atoms is divided into discrete portions, or quanta.
