Yes, the de Broglie equation relates the energy (E) of a particle to its wavelength (λ). The equation is given by:
E = h * c / λ
where: E is the energy of the particle, h is the Planck's constant (approximately 6.626 × 10^(-34) joule-seconds), c is the speed of light in a vacuum (approximately 3.00 × 10^8 meters per second), and λ is the wavelength of the particle.
The de Broglie equation shows that the energy of a particle is inversely proportional to its wavelength. A shorter wavelength corresponds to higher energy, while a longer wavelength corresponds to lower energy. This equation is based on the wave-particle duality principle, which suggests that particles can exhibit both wave-like and particle-like behavior.
