Presentation transcript:

Read the event described below, identify how many different waves were present.   Imagine that your family has just returned home from a day at the beach. You had fun playing in the ocean under a hot sun. You put some cold pizza in the microwave for dinner, and you turn on the radio. Just then, the phone rings. It’s your friend calling to ask about homework. With a seat partner, discuss your answers.

What are the characteristics of mechanical and electromagnetic waves? Introduction to Waves Essential Question: What are the characteristics of mechanical and electromagnetic waves? Instructional Approach(s): The teacher should introduce the essential question and the standard that aligns to the essential question

Use the PowerPoint to fill in the Waves graphic organizer as we discuss the characteristics of waves Instructional Approach(s): The teacher should give each student the Waves Notes sheet to use to record important information throughout the lesson

Rhythmic disturbances that carry energy without carrying matter What are Waves? Rhythmic disturbances that carry energy without carrying matter Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes

Types of Waves Mechanical Waves – waves that need matter (or a medium) to transfer energy A medium is the substance through which a wave can travel. Types of mediums: Gases, liquids, solids Examples: air, water, strings Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes

Some examples of Mechanical Waves Instructional Approach(s): The teacher should use the animations on the slide to reinforce mechanical waves.

Transverse Waves (mechanical) Definition: a wave vibrating at right angles to the direction it is travelling. Energy causes the matter in the medium to move up and down or back and forth at right angles to the direction the wave travels. Examples: waves in water, the stadium wave Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. The teacher should use the link to provide examples of mechanical waves.

Use the next four slides and your Wave Diagram sheet to label and define the parts of a Transverse wave. Instructional Approach(s): The teacher should give each student the Waves Notes sheet to use to record important information throughout the lesson. Students will be working with both graphic organizers.

Parts of a Transverse Wave The crest is the highest point on a wave. Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. Make sure that students are labeling the wave on the graphic organizer.

Parts of a Transverse Wave The trough is the valley between two waves, is the lowest point. Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. Make sure that students are labeling the wave on the graphic organizer.

Parts of a Transverse Wave The wavelength is the horizontal distance, either between the crests or troughs of two consecutive waves. Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. Make sure that students are labeling the wave on the graphic organizer.

Parts of a Transverse Wave The amplitude is the peak (greatest) value (either positive or negative) of a wave. The distance from the undisturbed level to the trough or crest. Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. Make sure that students are labeling the wave on the graphic organizer.

Parts of a Transverse Wave The rest position (or equilibrium) is the position that the medium would assume if there were no disturbance moving through it.  Rest Position Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. Make sure that students are labeling the wave on the graphic organizer.

An ocean wave is an example of a mechanical transverse wave Instructional Approach(s): The teacher should use the illustration on the slide to reinforce parts of a mechanical waves. Rest Postion (equilibrium)

Instructional Approach(s): The teacher should use the illustration on the slide to reinforce parts of a mechanical waves.

Transverse Wave

Compressional Wave (longitudinal) A mechanical wave in which matter in the medium moves forward and backward along the same direction that the wave travels. Ex. Sound waves A slinky is a good illustration of how a compressional wave moves Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. Make sure that students are labeling the wave on the graphic organizer.

Use the next three slides and your Wave Diagram sheet to label and define the parts of a Compressional wave.

Parts of a Compressional Wave (Longitudinal) Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. Make sure that students are labeling the wave on the graphic organizer. The compression is the part of the compressional wave where the particles are crowded together.

Parts of a Compressional Wave (Longitudinal) Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. Make sure that students are labeling the wave on the graphic organizer. The rarefaction is the part of the compressional wave where the particles are spread apart.

Parts of a Compressional Wave (Longitudinal) Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. Make sure that students are labeling the wave on the graphic organizer. The wavelength is the distance from compression to compression or rarefaction to rarefaction in a compressional wave.

Instructional Approach(s): The teacher should use the illustration on the slide to reinforce parts of a compressional wave.

Longitudinal Wave Also called Compression Wave

Comparison of Transverse and Longitudinal Waves

Electromagnetic Waves Waves that DO NOT NEED matter (medium) to transfer energy Examples: radiation, TV & radio waves, X-rays, microwaves, lasers, energy from the sun, visible light Why might electromagnetic waves be considered to be transverse waves? Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes. More to come on Electromagnetic waves…

Electromagnetic Waves

Electromagnetic Waves

Electromagnetic Spectrum The electromagnetic spectrum illustrates the range of wavelengths and frequencies of electromagnetic waves. Instructional Approach(s): The teacher should present the information. Teacher may use the electromagnetic spectrum sheet on the resource page to introduce electromagnetic spectrum.

Electromagnetic Spectrum Sheet Instructional Approach(s): The teacher should present the information. Teacher may use the electromagnetic spectrum sheet on the resource page to introduce electromagnetic spectrum.

Types of Waves Quad Clusters Ticket Out the Door Types of Waves Quad Clusters Instructional Approach(s): Each student should complete the summarizer. The teacher should use the summarizer to determine the level of student mastery and if differentiation is needed.
