BRAINCAKEDeBroglie Wavelength
In 1924 Louis de Broglie suggested that if light waves can behave as particles, then particles such as electrons should also behave as waves. He proposed that every moving particle has a wavelength, now called the de Broglie wavelength:
λ = h / p = h / mv
where λ is the wavelength (m), h is the Planck constant (6.63 × 10-34 J s), p is the momentum of the particle (kg m s-1), m is its mass (kg) and v is its speed (m s-1).
