# Write the relationship of de Broglie wavelength λ associated with a particle of mass m in terms of its kinetic energy K. - Physics

Short Note

Write the relationship of de Broglie wavelength λ associated with a particle of mass m in terms of its kinetic energy K.

#### Solution

Kinetic energy of the particle, K = 1/2 "mv"^2 = "P"^2/(2"m")

p = sqrt(2"mK")

de-Broglie wavelength of the particle λ = "h"/"p" = "h"/sqrt(2"mK")

Concept: Matter Waves
Is there an error in this question or solution?
