Core Idea - Waves and Their Applications in Technologies for Information Transfer

[HS.PHY.4.1] - Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling within various media. Recognize that electromagnetic waves can travel through empty space (without a medium) as compared to mechanical waves that require a medium. Clarification Statements: Emphasis is on relationships when waves travel within a medium, and comparisons when a wave travels in different media. Examples of situations to consider could include electromagnetic radiation traveling in a vacuum and glass, sound waves traveling through air and water, and seismic waves traveling through the Earth. Relationships include v = λf, T = 1/f, and the qualitative comparison of the speed of a transverse (including electromagnetic) or longitudinal mechanical wave in a solid, liquid, gas, or vacuum. State Assessment Boundary: Transitions between two media are not expected in state assessment.

Predecessor Standards:

  • 4.PS.4.1
    Develop a model of a simple mechanical wave (including sound) to communicate that waves (a) are regular patterns of motion along which energy travels and (b) can cause objects to move. Clarification Statement: Examples of models could include diagrams, analogies, and physical models. State Assessment Boundary: Interference effects, electromagnetic waves, or non-periodic waves are not expected in state assessment.

Same Level Standards:

  • RCA-ST.11-12.8
    Evaluate the hypotheses, data, analysis, and conclusions in a science or technical text, verifying the data when possible and corroborating or challenging conclusions with other sources of information.
  • AI.A-SSE.A.1
    Interpret expressions that represent a quantity in terms of its context.*
  • AI.A-SSE.B.3
    Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.
  • AI.A-CED.A.2
    Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.*
  • AI.A-CED.A.4
    Rearrange formulas to highlight a quantity of interest using the same reasoning as in solving equations (Properties of equality).* For example, rearrange Ohm’s law R=V2/P to solve for voltage, V. Manipulate variables in formulas used in financial contexts such as for simple interest, I=Prt.
  • AI.A-REI.B.3.a
    Solve linear equations and inequalities in one variable involving absolute value.
  • HS.ESS.1.2
    Describe the astronomical evidence for the Big Bang theory, including the red shift of light from the motion of distant galaxies as an indication that the universe is currently expanding, the cosmic microwave background as the remnant radiation from the Big Bang, and the observed composition of ordinary matter of the universe, primarily found in stars and interstellar gases, which matches that predicted by the Big Bang theory (3/4 hydrogen and 1/4 helium).
