This standard asks you to understand the big ideas of Modern Physics — things like how atoms work, how light behaves, and how energy relates to mass. You need to show you grasp these ideas and can explain how they connect to real situations, not just memorise definitions.
What to do, grades and common mistakes
- ·Explain how the Bohr model describes energy levels in atoms and what happens when electrons jump between them
- ·Describe the photoelectric effect and wave-particle duality, showing you understand when light acts like a particle or a wave
- ·Apply the concept of quantised energy and photons to explain atomic line spectra and ionisation
- ·Show understanding of nuclear physics concepts like binding energy, mass deficit, and conservation of mass-energy in nuclear reactions
- ·Connect ideas from relativity and particle physics (quarks, leptons, strong interaction, Coulombic repulsion) to explain modern physics phenomena
You demonstrate basic understanding of Modern Physics concepts by explaining simple phenomena like electron transitions or the photoelectric effect using appropriate terminology.
You provide in-depth explanations that show how different Modern Physics concepts relate to specific situations, demonstrating you understand the reasoning behind the phenomena rather than just the facts.
