Interactive HTML App (3 Tabs)

• Introduction (theory + visuals)
• Simulation (sliders + intensity graphs)
• Practice Quiz (auto-feedback)

Student Worksheet

• Guided theory questions
• Simulation investigations
• Calculation and IB-style explanations
• Screenshot tasks
• Reflection and summary section

Answer Key / Markscheme

• Step-by-step solutions
• IB-style marking guidance
• Accepted ranges and explanations

Topics Covered

• Single slit diffraction
• Double slit interference
• Diffraction grating (multiple slits)

How It Works

Students:

1. Open the interactive app (via link or QR code)
2. Work through three structured tabs:

• Learn the theory
• Explore simulations
• Complete quiz questions

3. Record their findings in the guided worksheet

Assessment & Use

This resource is ideal for:

✔ Inquiry-based lab activity
✔ Conceptual reinforcement
✔ Pre-exam revision
✔ Homework or flipped learning

Why Teachers Love It

• Combines theory + simulation + assessment in one activity
• Builds strong conceptual understanding, not just memorization
• Encourages student exploration and scientific reasoning
• Easy to implement — no installation required - just a web browser and the worksheet. (For iPad devices, first download the free Documents app from the App Store then download and open this App.)
