De Broglie Equation:
From: | To: |
The de Broglie equation describes the wave-particle duality of matter, stating that any particle with momentum has an associated wavelength. It was proposed by Louis de Broglie in 1924 and was fundamental to the development of quantum mechanics.
The calculator uses the de Broglie equation:
Where:
Explanation: The equation shows that the wavelength of a particle is inversely proportional to its momentum, with Planck's constant as the proportionality factor.
Details: Calculating the de Broglie wavelength is essential for understanding quantum behavior of particles, electron microscopy, and various applications in quantum physics and nanotechnology.
Tips: Enter the momentum in kg m/s. The value must be positive and non-zero. The calculator will compute the corresponding wavelength using Planck's constant.
Q1: What is wave-particle duality?
A: Wave-particle duality is the concept that every particle or quantum entity may be described as either a particle or a wave, exhibiting properties of both.
Q2: Why is Planck's constant important in this equation?
A: Planck's constant relates the energy of a photon to its frequency and serves as the fundamental constant connecting particle properties with wave properties.
Q3: What are typical wavelength values for common particles?
A: Macroscopic objects have extremely small wavelengths (undetectable), while subatomic particles like electrons have measurable wavelengths significant at atomic scales.
Q4: How does temperature affect de Broglie wavelength?
A: Higher temperatures increase particle momentum, which decreases the de Broglie wavelength according to the inverse relationship in the equation.
Q5: What are practical applications of de Broglie's hypothesis?
A: Electron microscopy, neutron diffraction, and various quantum technologies rely on the wave nature of particles described by de Broglie's equation.
