Overview

• Deals with geometrics and physical optics

• Includes:

  • Reflection

  • Refraction

  • Critical Angle

  • Electromagnetic

  • Visible Spectrum

  • Lenses

  • Mirrors

• Any type of calculator allowed

• Requires knowledge of SI Units - all answers require understanding of them

• Laser Shoot: Competitors must position mirrors around a barrier to reach a target on the wall

• Optics mainly focuses on light

Introduction

• Optics is a science that studies light

• Divided into 2 sub fields:

  • Geometric Optics

  • Physical Optics

• Geometric Optics:

  • Light is thought of as single rays rather than waves

  • Useful for explaining how light passes through materials such as glass or off mirrors

• Physical Optics:

  • Considers the wave nature of light rather than limited to single waves

  • Helps explain phenomena such as interference, diffraction, and refraction

  • Includes visible and electromagnetic spectrum

• Optics 2017 event focused more on geometric optics
