The experiment by Jnsson that showed the wavelikeproperties of electrons passing through a double slitis considered a pedagogically interesting experimentbut not a landmark experiment. Why do you supposethis is true?
Goals • To understand the interference of mechanical waves • To analyze standing waves on a string • To describe sound waves in terms of particle displacements or pressure variations • To calculate the speed of sound in different materials • To calculate sound intensity • To find what determines the frequencies of sound from a pipe • To see what happens when sound waves overlap • To investigate the interference of sound waves of slightly different frequencies Copyright © 2012 Pearson Education Inc.
