Lesson 1 — Intro

• Natuurkunde / Scheikunde
• Middelbare school
• havo, vwo
• Leerjaar 2

Learning goals:

•  voorkennis ophalen 
•  What is light? — Understanding waves and particles – wave particle duality
• — Light comes from light sources, and reflects of objects into our eyes
• — Light gets picked up by our eyes and the brain turns this into visual information about the room we are in. In Astronomy they use light to study the galaxy
• — light is energy — in the form of electromagnetic radiation.
• Light is a spectrum, visible light is only a small part of that.
• — wave ~ particle duality
