What is a Wave? Wave

A Wave is a disturbance that transfers energy from place to place. Back to Menu

What are the 2 types of waves? waves Give an example of each.

Transverse is like a rope. Longitudinal is like a slinky. Back to Menu

Explain how waves are created and give an example. What is a Medium? Medium

Waves are created when a source causes a medium to vibrate. A Medium is material that a wave can travel through. Back to Menu

Define Compressions and Rarefactions Draw a picture to illustrate your definition.

Compression is when waves are pressed closely together. Rarefaction is where the waves are spread out. Back to Menu Final Jeopardy

Name two of the four basic properties (not wave parts) parts of waves.

They are Amplitude, Amplitude Wavelength, Wavelength Frequency and Speed Back to Menu

Draw and diagram a transverse wave. There are 3 primary parts that should be labeled.

Crest is the highest point, the Trough the lowest. Wavelength is the distance from one crest to the next. Crest Back to Menu Trough Wavelength

What is Frequency and what is its unit? unit Draw an example of two waves: one with high frequency, frequency one with low

Frequency, Frequency measured in Hertz (Hz) Hz is the number of waves that pass in a certain amount of time. High Frequency Back to Menu Low

Define Amplitude How is a bow an example?

Amplitude is the maximum distance the medium carrying a wave moves from its resting point. Back to Menu Final Jeopardy

What is Reflection?

When an object or wave hits a surface it cannot pass through and bounces back. Back to Menu

What do each of these pictures represent? A B

Diffraction and Reflection Diffraction Reflection Back to Menu

Show Biff can hear Buff from around the corner. What is this called?

Diffraction: when a wave passes a barrier or opening, it bends and spreads out. Back to Menu

Explain what this picture represents and how it occurs.

Refraction, which is the bending of waves when the go from one medium to another. Changes the speed of the wave. Back to Menu Final Jeopardy

When two or more waves meet, their interaction is called…

Interference Back to Menu

What are two kinds of DAILY DOUBLE! Interference? Explain them.

Constructive (amplifies the sound) sound and Destructive (smaller amplitude). amplitude Back to Menu

What is this video an example of? Explain.

Resonance occurs when vibrations traveling through an object match the object’s natural frequency Back to Menu

Finish the equations: ? ? ?

Constructive Back to Menu Destructive Final Jeopardy

What are two types natural disasters that create powerful waves (one leads to the other…) other…

An Earthquake creates seismic waves. An underwater earthquake can trigger a Tsunami Back to Menu

What is the picture below an example of?

Retroreflection Back to Menu

What is sound? Explain, step by step, how we hear it. Use a tuning fork as an example.

Sound is created by Vibrations When you strike the tuning fork, it vibrates. The fork hits nearby air molecules, giving them the energy from the fork. Those molecules hit other, which hit others… like dominos! Finally, it reaches your ear. Back to Menu

While walking down the street, you notice an ambulance approaching. How does the sound of the siren change, why, and what is this called?

Doppler Effect means the pitch is higher as the object approaches (sound waves pile up closer), closer and lower as it passes (waves spread out). out Back to Menu Final Jeopardy

The more waves that pass a point in a given time, the higher the ____5____ , which is measured in __6__. Wave with the same ____7____ can amplify one another, causing _____8_____ interference. m/s 2 wavelength medium constructive Rarefaction refract wave Hz diffract Reflection frequency destructive

STOP

As a wave passes from one medium to another, it slows down. This causes it bend or refract. Reflection occurs when a wave cannot pass through an object. The more waves that pass a point in a given time, the higher the frequency, which is measured in Hz. Wave with the same wavelength can amplify one another, causing constructive interference.
