Detailed Summary
PHYSICS FORM FOUR CHAPTER ONE THIN LENSES. A lens is conventionally defined as a piece of glass which is used to focus or change the direction of a beam of light passing through it. They are mainly made of glass or plastic. Lens are used in making spectacles, cameras, cinema projectors, microscopes and telescopes. A lens which is thicker at its centre than at its edges converges light and is called convex or converging lens. A lens which is thicker at its edges than at its centre diverges light and is known as concave or diverging lens. Optical centre – this is the geometric centre of a lens which is usually shown using a black dot in ray diagrams. A ray travelling through the optical centre passes through in a straight line. Centre of curvature – this is the geometric centre of the circle of which the lens surface is part of.
Study Tips & Recommendations
Time Management
Practice under timed conditions to improve speed and accuracy. Allocate specific time limits to each section.
Active Practice
Attempt all questions before checking answers. Review mistakes to understand where improvements are needed.
Mark Scheme Review
Study marking schemes carefully to understand how examiners award points and structure your answers accordingly.
Regular Review
Schedule periodic reviews to reinforce learning and combat forgetting. Use spaced repetition for optimal retention.
