Optical instruments: JAMB Physics Past Questions and Answers
What the JAMB syllabus covers in Optical instruments
Our summary: How microscopes, telescopes, cameras and the eye work, and how lens power and sight defects are handled.
- General principles of microscopes, telescopes, projectors, cameras and the human eye (Physiological details of the eye are not required.)
- Power of a lens
- Angular magnification
- Near and far points
- Sight defects and their corrections
Objectives
- apply the principles of operation of optical instruments to solve problems;
- distinguish between the human eye and the cameras;
- calculate the power of a lens;
- evaluate the angular magnification of optical instruments;
- determine the near and far points;
- detect sight defects and their corrections.
