Strand 4: Modern Physics - Atomic and Nuclear
In this strand, students gain a deep appreciation of the evolving nature of physics as they turn their attention to the late 19th and early 20th centuries when unexplainable observations were challenging accepted theories and models. They learn how this period saw major developments in physics as experimental discoveries motivated by the need for explanations revolutionised the accepted understanding of the nature of matter on an atomic scale and led to a new area of study; namely quantum mechanics.
