De-Broglie's wavelength is:

Explanation

De-Broglie's wavelength equation, λ = h/p, relates the wavelength (λ) of a particle to its momentum (p) and Planck's constant (h). It suggests that every particle, including electrons, has a wave-like nature associated with it.In this equation, h represents Planck's constant, which is a fundamental constant in quantum mechanics. The momentum of a particle, represented by p, is the product of its mass and velocity.The equation tells us that the wavelength of a particle is inversely proportional to its momentum. This means that particles with higher momentum have shorter wavelengths, while particles with lower momentum have longer wavelengths.De-Broglie's wavelength equation is significant because it provides a connection between the particle and wave properties of matter. It helps us understand phenomena like electron diffraction, where electrons behave as waves and exhibit interference patterns.
