Problem 1PE
Matter Waves
What is the wavelength of an electron moving with a speed of 5.97 * 106m/s? The mass of the electron is 9.11 x 10-31 kg.
Consider the following three moving objects: (i) a golf ball with a mass of 45.9 g moving at a speed of 50.0 m/s, (ii) An electron moving at a speed of 3.50 * 105m/s, (iii) A neutron moving at a speed of 2.3 x 102m/s. List the three objects in order from shortest to longest de Broglie wavelength, (a) i< iii< ii (b) ii< iii< i (c) iii< ii< i (d) i< ii< iii (e) iii< i< ii

ANSWER:
Step 1 of 4
De Broglie stated that when an electron moves around a nucleolus it follows wave properties.
So, the relation between mass of neutron and wavelength will be as follows:
