PHYS.PS4: Waves and Their Applications in Technologies for Information Transfer

1) Know wave parameters (i.e., velocity, period, amplitude, frequency, angular frequency) as well as how these quantities are defined in the cases of longitudinal and transverse waves.

2) Describe parameters of a medium that affect the propagation of a sound wave through it.

3) Understand that the reflection, refraction, and transmission of waves at an interface between two media can be modeled on the basis of characteristics of specific wave parameters and parameters of the medium.

4) Communicate scientific and technical information about how the principle of superposition explains the resonance and harmonic phenomena in air columns and on strings and common sound devices.

5) Evaluate the characteristics of the electromagnetic spectrum by communicating the similarities and differences among the different bands. Research and determine methods and devices used to measure these characteristics.

6) Plan and conduct controlled scientific investigations to construct explanations of light’s behavior (reflection, refraction, transmission, interference) including the use of ray diagrams.

7) Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model.

8) Obtain information to construct explanations on how waves are used to produce, transmit, and capture signals and store and interpret information.

9) Investigate how information is carried in optical systems and use Snell’s law to describe the properties of optical fibers.
