Find the ratio of the wavelength of incident light to the de-Broglie wavelength of the fastest photoelectron emitted. It is observed that the photoelectron emission stop at a certain time t after the light source is switch on. Why? Evaluate the time t. (If , make sure the precision of your calculator sufficient or use the non-relativistic method below.) If you know that the particle is super-relativistic, so that , then just use and life is easy.. If you know that the particle is highly non-relativistic, , then you can use giving .. So, for example, compute the wavelength of a 100 eV electron. This is non-relativistic since 100 eV « 510000 e 2008-05-11 You should expect the de Broglie wavelength of a macroscopic object to be extremely small—so small, in fact, that you might think it was a mistake if you didn’t know what to expect.

Code to add this calci to your website . Formula : λ = h / (m×v) Where, λ = Wave length h = Plank's Constant (6.62607 x 10-34) m According to de broglie wavelength and velocity of particles are inversely proportional to each other.

For massive, non-interacting particles, the thermal de Broglie wavelength can be derived from the calculation of the partition function.Assuming a 1-dimensional box of length L, the partition function is (using the energy states of the 1D particle in a box): = ∑ − / = ∑ − / Since the energy levels are extremely close together, we can approximate this sum as an integral: The wavelength of a particle, given by \lambda = {h\over p}, where h is Planck's constant and p is the momentum. In the nonrelativistic limit, this can be written \lambda={h\over mv}, where m is the particle mass and v is the velocity.
