As Prof. Greene indicated in his lecture , the double slit experiment teaches us that microscopic objects , like electrons , are both particles and waves .In fact, as Prof . Greene also described , Louis de Broglie suggested in 1923 that all material objects display wave -lil(e properties and have wavelengths associated with them .According to de Broglie ,these "matter waves " have a h wavelength given by the equation a '3 =, where A is the wavelength of the object , h is Planck's mu constant , m is the mass of the object , and v is its speed .Let's consider what this formula and its application tell us about the electrons in our double slit experiment C. (i) Suppose that in your double slit experiment , your electrons are moving at a speed of 1 km/s. What is the wavelength of these electrons in units of nm '3 (ii) Do the electrons in your double slit experiment behave ONLY as waves ? Give your answer as YES or NO and explain how you know in 1-2 sentences D. An object's "wave -like " properties are manifest on scales comparable to (or smaller than) their de Broglie wavelength .On scales much larger than its de Broglie wavelength , an object behaves more like a particle .In 2012 researchers at the University of Nebraska -Lincoln performed the double -slit experiment , exactly as it was described in the lecture . Electrons were fired by an electron gun and passed through a wall with two slits , which were ~270 nm apart from each other . (i) How does the wavelength that you calculated in part C (i) compare to the slit separation used in the University of Nebraska -Lincoln experiment ? Select from the options below : a. It is larger . b. It is smaller . c. It is equal . d. It cannot be determined
