Matter Waves What is the wavelength of an electron moving with a speed of 5.97 * 106m/s? The mass the electron is 9.11 x 10-31 kg. Calculate the velocity of a neutron whose de Broglie wavelength is 505 pm. The mass of neutron is given in the table inside the back cover of the text.

Solution: Here, we are going to calculate the velocity of the neutron whose de-Broglie wavelength is 505 pm. Step1: According to de-Broglie, the wavelength associated with a particle of mass m, moving with velocity v is given by, --------(1) Where, = wavelength of the particle -34 H = Planck’s constant and its value is 6.626 x 10 J.s v = velocity of the particle Step2: Given, wavelength of the...
