Monday, January 4 th Entry Task For each situation below, explain, using full sentences, what might happen to show that the waves transfer energy. 1.A seaside beach in a storm 2.An earthquake 3.Movement of coils Schedule: Sound Homework Read/RSG 16.1 Objective: I can understand that sound is a wave

Tuesday, January 5 th Entry task: Decide if the following statements are true. If they are, write them down as is. If they are false, write down a correct statement. 1.In a longitudinal wave, the vibrations move perpendicular to the direction of the wave 2.Sound is a type of electromagnetic wave. 3.Vibrations pass through many parts of the ear, not just the eardrum. Schedule: 16.1 Notes 16.1 RKC/CE Homework: 16.1 review questions 1-6. Full sentences, IQIA Objective: I can understand that sound is a wave and how its produced and detected. Please have on your desk: 16.1 RSG

What is Sound? Sound is produced by vibrations. –A vibration is a complete back-and-forth motion of an object.

Sound travels as longitudinal waves Sound waves travel in all directions away from their source. In a longitudinal wave, the particles vibrate back and forth along the same path that the wave travels. However, the air or other matter through which the wave is traveling does not travel with the sound waves. The particles of air only vibrate back and forth. Longitudinal waves consist of compressions and rarefactions.

This is how a speaker produces sound

Sound Waves Require a Medium! Sound and Media All sound waves require a medium (plural, media). A medium is a substance through which a wave can travel by vibrating particles in the material. Air is the most common medium of sound waves. There are no particles to vibrate in a vacuum. So, no sound can be made in a vacuum.

16.1 Sound is a Wave Do RKC and CE worksheet –ISN Review questions –From page 523 –#1-6 –Use full sentences, IQIA. –ISN 86 Re-read 16.1 and review 16.1 RSG

Wednesday, January 6 th Entry Task Start silently reading 16.2 Schedule: 16.2 Notes Homework: 16.2 RSG Objective: I can understand that frequency determines pitch Please have on your desk 16.1 RKC/CE 16.1 Questions

The speed of sound depends on the medium The speed of sound depends only on the medium in which the sound is traveling. Sound travels quickly through air, but it travels even faster in liquids and even faster in solids. Why? Think about how close together the particles are!

Pitch depends on frequency How high or low you perceive a sound to be is the PITCH of that sound. Humans can generally hear sounds that have frequencies between 20 Hz and 20,000 Hz.

Frequencies you can’t hear Frequencies below 20 Hz are called INFRASONIC. Frequencies above 20,000 Hz are called ULTRASONIC.
