Introduction
How are we able to see objects through glass surfaces? This PSLE Science Light Reflection From Glass Question helps students understand how light behaves when it meets transparent materials.
In this PSLE Science Light Reflection From Glass Question, students must identify how light allows us to see objects through glass using reflection concepts.
The Question
Sue looked into a wooden cupboard through a glass panel.
Which statement explains why she can see the objects through the glass?
Step-By-Step Explanation (Teacher Board Working)
Step 1 — How Vision Works
To see objects:
Light must enter our eyes.
Step 2 — What Happens When Light Hits Glass
When light hits glass:
- Some light passes through (transmission)
- Some light is reflected
Teacher focuses on:
👉 Light reflected from glass into eyes
Step 3 — Why Sue Can See
Light from inside cupboard:
➡ Travels towards glass
➡ Some light reflects off glass surface
➡ Reflected light enters her eyes
Step 4 — Match With Options
Correct statement:
✔ Some light is reflected from the glass
✅ Final Answer
✔ Option 4
Key Concepts
Reflection of Light
Light bouncing off surfaces into our eyes.
Transparent Materials
Allow light to pass through but also reflect some light.
Examples:
- Glass
- Water
- Clear plastic
Why Reflection Matters Here
Even transparent surfaces reflect some light — this is why we can see glass surfaces too.
Tips for Students
✔ If question asks about seeing surface → Think reflection
✔ If question asks about seeing through → Think transmission
✔ Glass → Both reflection + transmission
For Parents
This topic develops:
- Scientific reasoning
- Concept application
- Exam answering confidence
Light behaviour questions appear frequently in PSLE Science.
Conclusion
This PSLE Science Light Reflection From Glass Question teaches students that even transparent materials reflect some light.
Key Learning:
✔ Light reflection allows objects to be seen
✔ Glass reflects AND transmits light
Mastering this PSLE Science Light Reflection From Glass Question helps students score better in PSLE Science exams.
