This page contains a set of 67 concept (clicker) questions with answer key on the topic of waves, available for free download in Power Point or pdf format. It is a PhET Gold Star award-winning resource, developed for use with PhET interactive simulations on waves. Concept questions are intended to introduce a topic and probe students' existing beliefs prior to formal instruction. Students discuss their viewpoints, then "vote" on the correct response to the concept question. The use of concept questions has been extensively tested by physics education researchers and correlated with improved learner outcomes. The clicker questions were created specifically to supplement the following PhET simulations: Fourier: Making Waves, Sound, Wave on a String, Wave Interference, Geometric Optics, and Resonance. This resource is part of a set of teacher-created materials developed to supplement the PhET collection of interactive physics simulations.

Construct viable arguments and critique the reasoning of others.

Use functions to model relationships between quantities.

Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.

Create equations that describe numbers or relationships

Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.

Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations.

Interpret functions that arise in applications in terms of the context

For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship.?

Construct and compare linear, quadratic, and exponential models and solve problems

Distinguish between situations that can be modeled with linear functions and with exponential functions.

Recognize situations in which one quantity changes at a constant rate per unit interval relative to another.

Model periodic phenomena with trigonometric functions

Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline.?
