BELL WORK Create a hypothesis about amplitude

using a pool of water and rocks.

THE GAME OF BLUFFRules 1. Two teams: 2 front rows/2 back rows2. One team is offered a question, everyone who

thinks they know the answers stands up. *You receive a point for every person who stands up.

3. Last person to answer from the other teams picks who they want to answer. So you may not want to stand if you aren’t sure.

4. A missed answer is open for a steal.5. Any talking results in points awarded to the

opposite team.6. Winning team receives 5 extra credit points on

test

READY

. A disturbance that transfers energy from one place to another. wave

Measure of how far the particles in the medium move away from their normal rest position.

amplitude

The distance from any point on a wave to an identical point on the next wave

wavelength

What is the amplitude of the wave inthe picture if each square is a cm?

4 Centimeters

The time required for one wavelength to pass a given point. wave period

A way to express the time of a wave’s cycle is.

Frequency

Unit of measurement for frequency). One equals one wavelength per second

hertz

Many waves spreading out in circles or spheres

wavefronts

Waves tend to travel more slowly in this type of medium.

denser

This is the distance divided by time

Speed

What is the name of the surfer’s location on the wave?

CREST

This unit of measurement equals its wavelength divided by its period.

speed of a wave

. A wave is cresting every 6 Meters and has a frequency of 0.5 Hz. What is the speed of the

waves?

3 m/s

In a vacuum, how do we know the speed of electromagnetic waves?

In a vacuum all waves travel at the speed of light

The time it takes for one wavelength to pass a point

Wave period

What is the name of the surfer’s location on the wave?

Trough

As the air gets colder in the winter, sound would travel

Slower

What is the wave length of the wave in the picture?

6 centimeters

A wave a the beach first comes to your ankles, as the tide comes

in the wave increases the the haight of the knees. Which has

changed with the wave?

Amplitude

When an earthquake occurs, many animals respond prior to the movement of the ground,

what are the feeling?

(P) Primary Wave

What is wave we are feeling when an earth quake rattles buildings? (S) Secondary Wave

What are the circles of waves in the picture demonstrating?

Wave front
