2.3.37 - Wave graphs

Be able to draw and interpret graphs representing transverse and longitudinal waves including standing/stationary waves.

Use - wave graphs to connect the rule to the data and decision in the question.

This matters because - wave graphs determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - wave graphs to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Wave graphs is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
