`a)` Name the experiment for which the adjacent graph, showing the variation of intensity of scattered electrons with the angle of scattering `(theta)` was obtained. `b)` Also name the important hypothesis that was confirmed by this experiment.

Name the experiment which shows that light was wave property.

Name the experiment, which establish the wave nature of moving electrons.

Name the experiment which shows that light has particle property.

Draw a graph showing the variation of intensity verses the position on the screen in Young's experiment, when one of the slits is closed.

a. Name the experiment which establishes the wave nature of moving electrons. b. In that experiment, electrons are accelerated through a potential of 54 V and is made to fall normally on the nickel crystal of interatomic separation 0.91 A. Draw the polar graph showing the variation of intensity of the scattered electrons electrons and latitude angle at this potential. c. Calculate the d-Broglie wavelength of the electron.

Draw a labelled graph to show variation in intensity of diffracted light with angular position, in a single slit diffraction experiment.
