Contents & notes: what this topic covers
Under Light Energy, the JAMB Physics syllabus expects you to study:
- 23. Light Energy
- (a) Sources of Light
- (i) natural and artificial sources of light;
- (ii) luminous and non-luminous objects.
- (b) Propagation of light
- (i) speed, frequency and wavelength of light;
- (ii) formation of shadows and eclipse;
- (iii) the pin-hole camera.
Study notes & guidance
Study Light Energy using a recommended Physics textbook that follows the JAMB syllabus. Work through the contents listed above one by one, make brief notes in your own words, and then practise as many questions on this topic as you can — in Physics, understanding and steady practice matter far more than memorising. Use the objectives below as a checklist: if you can do each one confidently, you have mastered this topic.
Objectives — candidates should be able to
After studying Light Energy, you should be able to:
- Compare the natural and artificial sources of light;
- Differentiate between luminous and non luminous objects;
- Relate the speed, frequency and wavelength of light;
- Interpret the formation of shadows and eclipses;
- Solve problems using the principle of operation of a pin-hole camera.
These objectives are from the official JAMB syllabus. Use them as a checklist — if you can do each one confidently, you have mastered this topic.
