Phenomenon

Overarching Question: Why are we able to hear the sound but not see the light? Beginning ideas/mental model Discussion – what do we need to know in order to explain the phenomenon?

Part I: What are waves, and how do they transfer energy? Beginning Ideas Investigations Discussion

Types of Waves Video Clip of Types of Waves – see desktop Transverse Longitudinal Transverse Water Waves Video Clip of Types of Waves – see desktop

Electromagnetic Wave From: http://www.srh.noaa.gov/jetstream/remote/images/emwave.gif

Sound waves vs. light waves Sound waves: mechanical waves Restorative force = molecules returning to equilibrium Light waves: Electromagnetic waves Restorative force = propagation by interactions between electric field and magnetic field

Wave energy intensity vs. distance From: https://en.wikipedia.org/wiki/Inverse-square_law#/media/File:Inverse_square_law.svg

Part I: Terminology Wave pulse Periodic wave Mechanical wave Electromagnetic wave Medium Transverse waves Longitudinal waves Energy transfer Disturbance Restoring force Equilibrium

Part II: What are identifying characteristics of waves, and what factors influence them? Beginning Ideas Investigations Discussion

Wave Properties

Terminology & Units Frequency (f): cycles/second (hertz) (Hz) Wavelength (λ): meters Wave Speed (V): meters/second Amplitude: Depends on the type of wave : Water wave: amplitude is a displacement (distance) Sound wave: amplitude is in terms of loudness (air pressure) Light wave: amplitude is in terms of brightness (intensity) Audible Sound λ: Visible Light :

What influences properties of waves? Beginning Ideas Investigations Discussion

Relationships Wave formula: V = fλ Wave Formula: V = fλ Amplitude: Amount of energy applied

Relationships (cont.) Speed and Medium Speed of a wave depends on the elasticity or stiffness of the medium Sound (m/s) Light (m/s) Water 1,498 224,310,000 Air 343 299,700,000 Vacuum 299,792,458
