Question

ch9. q1
who predicted that all matter can behave as waves as well as particles?
erwin schrodinger
albert einstein
louis de broglie
max planck

Explanation:

Louis de Broglie proposed the de Broglie hypothesis. This hypothesis states that all matter has wave - like properties. The de Broglie wavelength formula is $\lambda=\frac{h}{p}$, where $h$ is Planck's constant and $p$ is the momentum of the particle. Erwin Schrödinger developed the Schrödinger equation which describes the wave - like behavior of quantum systems. Albert Einstein is known for the theory of relativity (special and general) and the photoelectric effect. Max Planck is famous for introducing the concept of quantization of energy ($E = h
u$).

Answer:

Louis de Broglie
