Transverse and Compressional Waves

Curriculum Big Idea: Waves carry energy from one location to another without the transfer of matter. Big Idea: Waves carry energy from one location to another without the transfer of matter. Concept: Mechanical waves can be classified according to their movement, standing or compression, and according to their direction of oscillation, which can be transverse or longitudinal. Concept: Mechanical waves can be classified according to their movement, standing or compression, and according to their direction of oscillation, which can be transverse or longitudinal. PA Standard: B5: Understand that waves transfer energy without transferring matter.

Today’s Agenda Opener: Watch the Galloping Gertie video, and answer the “What Do You Think?” Questions in the 5.1: Waves and Energy packet Opener: Watch the Galloping Gertie video, and answer the “What Do You Think?” Questions in the 5.1: Waves and Energy packet Define the following Physics Words in your packet: wave, transverse wave, compressional (longitudinal) wave Define the following Physics Words in your packet: wave, transverse wave, compressional (longitudinal) wave For You To Do Part I: Transverse vs. Longitudinal For You To Do Part I: Transverse vs. Longitudinal 1. Make a “people wave,” like at a Phillies game, and answer #1 a-e in the packet. Discuss your answers in small groups and as a class. 2. Make a different people wave by following the instructions from the teacher. Answer #2 a-d in the packet. Discuss your answers in small groups and as a class. Electricity Review Electricity Review Closure: What is the difference between a transverse wave and a compressional (longitudinal) wave? Closure: What is the difference between a transverse wave and a compressional (longitudinal) wave? Take Home Assignment: Answer the Physics To Go questions #1-2 in the Unit 5.1 packet.

Today’s Physics Vocabulary Wave – a wiggle in space and time. Transfers energy without transferring matter. Wave – a wiggle in space and time. Transfers energy without transferring matter. Transverse wave – a wave in which the vibrations are at right angles to the direction the wave (pulse) travels. Transverse wave – a wave in which the vibrations are at right angles to the direction the wave (pulse) travels. Compressional (longitudinal) wave – a wave in which the vibrations travel in the same direction that the wave (pulse) travels. Compressional (longitudinal) wave – a wave in which the vibrations travel in the same direction that the wave (pulse) travels.
