Calculate the wavelength of a neutron that has a velocity of 200. cm/s. (the mass of a neutron = 1.675 * 10-27 kg and h = 6.63 * 10-34 j s).

To find the wavelength of a neutron can be calculated by using the formula Wavelength=h/m x v Where h is planck's constant m=mass of neutron v = velocity of the particle By substituting the given values Wavelength = 6.63 * 10-34 j s / 1.675 * 10-27 kg x 2 m/s^-1 Wavelength of a neutron=1.979 x 10^-7 m
