The difference between Schrödinger and de Broglie is based on their contributions to quantum mechanics, although both are related to the wave nature of particles. Here's a simple breakdown of each:
1. Louis de Broglie (De Broglie Hypothesis):
- What he proposed: In 1924, de Broglie suggested that not just light (which had already been shown to have wave-like properties) but all matter, including particles like electrons, also has wave-like properties. This idea is known as the de Broglie hypothesis.
- Main Idea: He proposed that particles such as electrons can behave like waves, and the wavelength (\( \lambda \)) of a particle is related to its momentum (\( p \)) by the formula:
\[
\lambda = \frac{h}{p} = \frac{h}{mv}
\]
Where:
- \( \lambda \) = wavelength
- \( h \) = Planck's constant
- \( p \) = momentum (mass \( \times \) velocity)
- \( m \) = mass of the particle
- \( v \) = velocity of the particle
Significance: The de Broglie wave concept helped lay the foundation for the idea of wave-particle duality (that particles can act as both particles and waves). This idea was later confirmed by experiments like electron diffraction.
2. Erwin Schrödinger (Schrödinger Equation):
- What he proposed: Schrödinger, in 1926, developed a mathematical framework to describe the quantum behavior of particles. His famous equation, called the Schrödinger equation, describes how the quantum state of a system evolves over time.
- Main Idea: Schrödinger's equation doesn't directly talk about wave-particle duality like de Broglie, but it describes the behavior of the wave function (which is a mathematical description of a quantum system). The wave function can be used to find the probability of a particle's position and other properties.
- The equation looks like this (time-independent form):
\[
\hat{H} \Psi = E \Psi
\]
Where:
- \( \hat{H} \) = Hamiltonian operator (energy operator)
- \( \Psi \) = Wave function (describes the probability of a particle’s state)
- \( E \) = Energy of the system
Significance: Schrödinger's equation allows us to calculate the behavior of quantum systems, such as electrons in atoms, and find information about energy levels, probabilities, and more.
The Key Difference:

- De Broglie introduced the idea of matter waves (wave-particle duality) and proposed a relationship between a particle’s momentum and its wavelength.
- Schrödinger provided the mathematical framework (the Schrödinger equation) to describe how these wave-like properties evolve and how the behavior of quantum particles can be predicted.
In simpler terms:
- De Broglie gave the idea that particles can have wave-like behavior.
- Schrödinger provided the tool (the equation) to describe and predict how these "waves" behave.
