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.

6-8: 4E/M2. Energy can be transferred from one system to another (or from a system to its environment) in different ways: 1) thermally, when a warmer object is in contact with a cooler one; 2) mechanically, when two objects push or pull on each other over a distance; 3) electrically, when an electrical source such as a battery or generator is connected in a complete circuit to an electrical device; or 4) by electromagnetic waves.

4F. Motion

6-8: 4F/M4. Vibrations in materials set up wavelike disturbances that spread away from the source. Sound and earthquake waves are examples. These and other waves move at different speeds in different materials.

6-8: 4F/M5. Human eyes respond to only a narrow range of wavelengths of electromagnetic waves-visible light. Differences of wavelength within that range are perceived as differences of color.

6-8: 4F/M6. Light acts like a wave in many ways. And waves can explain how light behaves.

6-8: 4F/M7. Wave behavior can be described in terms of how fast the disturbance spreads, and in terms of the distance between successive peaks of the disturbance (the wavelength).

9-12: 4F/H6ab. Waves can superpose on one another, bend around corners, reflect off surfaces, be absorbed by materials they enter, and change direction when entering a new material. All these effects vary with wavelength.

9-12: 4F/H6c. The energy of waves (like any form of energy) can be changed into other forms of energy.

Topic: Wave Energy Unit Title: Teaching About Waves and Wave Energy

This PhET Gold Star-winning resource is a set of 60+ Power Point concept questions on the topic of waves, available for free download. They were created by a high school physics teacher to be used with three PhET simulations: Wave on a String, Fourier Analysis, and Sound. Concept questions are designed to introduce a topic and probe student understanding BEFORE formal instruction. This method has been correlated with improved learner outcomes in studies conducted by physics education researchers.
