The exam paper explores advanced physics concepts, including light refraction through lenses, wave properties, stopping distances, and electromagnetic phenomena. Key topics include convex and concave lenses, wave speed calculations, and factors affecting vehicle braking distance. Questions cover electromagnetism with solenoids and electromagnets, Big Bang theory evidence via red-shift, and the effects of inertia and safety surfaces. Additional sections analyze infrared radiation, albedo, free body diagrams, skydiver motion, and ultrasound applications. Practical applications emphasize experimental methods, data analysis, and mathematical problem-solving. Keywords: lenses, wave properties, braking distance, electromagnetism, red-shift, inertia, safety surfaces, infrared radiation, ultrasound, Big Bang theory.
