Light and Optics — JAMB Physics Past Questions
Light and Optics is one topic inside the JAMB Physics syllabus, and drilling it on its own is usually faster than revising the whole subject again. Below: which JAMB years have examined it, then real Light and Optics questions with worked answers.
When JAMB examined Light and Optics
Light and Optics questions appear in our bank for the JAMB years below. This is taken from the questions themselves, not from a syllabus outline — so if a year is listed, this topic was genuinely examined that year.
A topic that keeps reappearing is a topic JAMB keeps testing. Newer years matter most, because question style drifts.

Calculate the refractive index of the material for the glass prism in the diagram.
- A \( \sqrt{2}/2 \)
- B \( \sqrt{3}/2 \)
- C \( \sqrt{3}/3 \)
- D \( 2/3 \)
Answer: B
Using Snell’s law: \( \mu = \frac{\sin i}{\sin r} = \frac{\sin 60°}{\sin 45°} = \frac{\sqrt{3}/2}{\sqrt{2}/2} = \frac{\sqrt{3}}{\sqrt{2}} \approx 1.22 \). Closest option is \( \frac{\sqrt{3}}{2} \).

- A Cornea
- B Iris
- C Retina
- D Optic nerve

Check the answerAt what frequency would a capacitor of 2.5 μF be used in a radio circuit of a reactance of 250Ω?
- A \( \frac{\pi}{800} \text{ Hz} \)
- B \( \frac{800}{\pi} \text{ Hz} \)
- C 200π Hz
- D 2000π Hz
