The curriculum for Physics IBDP is designed in such a way to bring students and readers alike to the frontiers of modern science and elevate the spirit of scientific inquiry in their minds. The topics in the syllabus range from the ancient science of the Greeks to modern disciplines like Atomic and Astrophysics, which makes the students aware of the entire spectrum of the discoveries and advances in Physics alongside the rationale and its purpose. As such the chapters are divided by classical and modern distinctions: classical chapters include Newtonian Mechanics describe the original theories of motion and movement, Thermodynamics talk about our original assumptions of ideal gas and principles of heat and temperature, while Electrodynamics cover the interconnected universe of electricity, magnetism and electromagnetic waves, and the various properties and phenomena associated with them.

In contrast lies the topics of Modern Science, ranging from Atomic, Nuclear and Particle Physics to the more advanced study of motion in Einstein’s Relativity and Quantum Mechanics. A complete understanding of these topics will render any reader with the amazing ability to apply Physics to every corner of life, ranging from the mundane to the extraordinary; prepare them prepare them for only a future in an advanced scientific discipline, but also in fields like Economics, Finance and Technology, all of which require a scientific mindset at their core. 

In this chapter of Imaging Theory, we develop the topic of ray optics and its various applications in widely used instruments. We are introduced to concepts in image formation through lenses like the focal length and curvature of a lens, the mirror formula and magnification of any lens, and aberrations (chromatic and instrumental) that produce errors in imaging.

We then use these newly developed concepts to study the working of instruments like an optical compound microscope and astronomical reflecting and refracting telescopes. We finally move to modern applications like fiber optical transmissions, X-ray and computed tomography used to image the body and ultrasound and nuclear magnetic resonance imaging (MRI).
