Relevance? 9 years ago. Favorite Answer. (a) Given,Mass of the bullet, m = 0.040 kgVelocity with which the bullet is travelling, v = 1 kms-1 = 103 ms-1Using the formula of momentum, p = mv = 0.040 × 103 = 40 kg ms-1∴ De-broglie wavelength is, λ = hp = 6.62 × 10-3440 = 1.7 × 10-35m (b) Mass of the ball, m = 0.060 kg Velocity with which the ball is moving, v = 1.0 ms-1 Momentum of the particle, p = mv = 0.060 kg ms-1Therefore, De Let $\lambda_1$ be the de-Broglie wavelength of the proton and $\lambda_2$ be the wavelength of the photon. The ratio $\lambda_1/\lambda_2$ is proportional to For an electron with KE = 1 eV and rest mass energy 0.511 MeV, the associated DeBroglie wavelength is 1.23 nm, about a thousand times smaller than a 1 eV photon.

Substituting the value of v. λ = h/ rt (2meV) .. (a) Given,Mass of the bullet, m = 0.040 kgVelocity with which the bullet is travelling, v = 1 kms-1 = 103 ms-1Using the formula of momentum, p = mv = 0.040 × 103 = 40 kg ms-1∴ De-broglie wavelength is, λ = hp = 6.62 × 10-3440 = 1.7 × 10-35m (b) Mass of the ball, m = 0.060 kg Velocity with which the ball is moving, v = 1.0 ms-1 Momentum of the particle, p = mv = 0.060 kg ms-1Therefore, De Free PDF download of Formulas for De Broglie Wavelength Formula to score more marks in exams, prepared by expert Subject teachers from the latest edition of CBSE books.

Looking at the equation, as the speed of the electron decreases, its wavelength increases. The de Broglie equations relate the wavelength λ to the momentum p, and frequency f to the total energy E of a free particle: λ = h / p f = E / h {\displaystyle {\begin{aligned}&\lambda =h/p\\&f=E/h\end{aligned}}} Here h is the Planck’s constant and its value is 6.62607015×10-34 J.S The formula for λ is known as the de Broglie wavelength of the electron. By analyzing this we can say that slowly moving electrons are having the large wavelength and fast-moving electrons are having a short or minimum wavelength.
