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
