Gold foil experiment class 9
http://cdac.olabs.edu.in/?sub=75&brch=12&sim=88&cnt=1 WebIn Rutherford’s experiment, he bombarded high energy streams of α-particles on a thin gold foil of 100 nm thickness. The streams of α-particles were directed from a radioactive source. He conducted the experiment to study the deflection produced in the trajectory of α-particles after interaction with the thin sheet of gold.
