General Physics Q&As

This past questions and answers collection in General Physics is designed to help HND Network Security students revise the key physics concepts that support modern electronic and communication systems. It focuses on Electrostatics (electric fields, charges, potentials), Waves (mechanical and electromagnetic waves, frequency, wavelength, interference), Capacitors (capacitance, charging/discharging, energy storage in circuits), and Optics (reflection, refraction, lenses, image formation). By working through real exam-style questions with clear, step-by-step solutions, students can strengthen their problem‑solving skills, understand how these topics underlie networking and signal transmission, and prepare confidently for their HND examinations.
