Allowed materials: see course syllabus. • A practice exam is available on CUlearn. Today (and next class) : Basic properties of light (aka. electromagnetic waves ): – How to generate light – Wave-like properties of light – Next week: Particle-like properties of light Disclaimer: A very exciting part of this course is the particle-wave duality of light (and matter!) However, do not get confused with when to use the wave or the particle representation of the very same physical entity. It actually depends on the experiment (‘question’ or ‘measurement’)! We will see several experiments that should help you understand this concept. Strap in and enjoy the ride! Properties of light Interaction with matter When does an electric field exert a force on a charge? a) Always b) Sometimes (only static electric fields) Q1 c) Sometimes (only alternating fields) d) Sometimes (depends on the sign of the charge) e) Never or only rarely f) Something completely different Properties of light Interaction with matter Electric fields exert forces on charges F=qE + (e’s and p’s in atom)...
