PSc.3.2.1
• Identify the basic characteristics of a longitudinal (compressional) wave: amplitude, rarefaction, and compression.
• Recognize the relationship between period and frequency (focus on conceptual understanding of this inverse relationship).
• Explain the relationship among velocity, frequency, and wavelength and use it to solve wave problems:
• Exemplify wave energy as related to its amplitude and independent of velocity, frequency or wavelength.
PSc.3.2.2
• Classify waves as one of three types: mechanical, electromagnetic or surface waves based on their characteristics.
• Compare different wave types based on how they are produced, wave speed, type of material (medium) required, and motion of particles.
PSc.3.2.3
•Compare compressional (longitudinal) and transverse waves in terms of particle motion relative to wave direction.
PSc.3.2.4
• Illustrate reflection and refraction of waves at boundaries: reflection of a transverse pulse at the fixed-end of a spring or rope; reflection of sound (SONAR) and radio waves (RADAR); reflection of water (surface) waves; refraction of water waves as the depth of the water changes; sound as it changes media; refraction of light as it passes from air into water, glass, oil etc.
• Illustrate the effects of wave interference (superposition)–constructive and destructive interference of surface waves, mechanical waves (sound, pulses in springs/ropes, etc.), light (soap bubbles/thin films, diffraction gratings). Emphasis is on conceptual understanding – not mathematical relationships.
