100
The material that waves travel through
Medium/Media
100
When particles in a wave move in a circular motion
surface wave
100
When a wave travels through a medium
transmission
100
What are the peaks and dips of a wave called?
peaks= crest
dips= trough
100
How would you draw/model a loud sound vs. a quiet sound?
loud sound: waves with high amplitude (tall)
quiet sound: waves with low amplitudes (short)
200
Scientists use lines with arrows to model sound, what do we call these symbols?
rays
200
When particles move parallel to the wave (back and forth)
longitudinal wave
200
When a wave bounces off a new medium
reflection
200
This word describes the height of a wave
amplitude
200
Which sound behavior explains why we hear echos?
Reflection
300
What are the units for frequency
Hertz (Hz)
300
In a transverse wave, particles move ____.
perpendicular to the direction that the wave moves
300
When a wave loses some of its energy because the energy is transferred to other objects
absorption
300
The distance from one crest to the next crest is called ___
wavelength
300
What is the relationship between a wave's frequency and wavelength?
As frequency increases, wavelength decreases.
As frequency decreases, wavelength increases.
400
When a wave has no energy/motion, it can be drawing as a flat horizontal line. We call this the _____.
resting position
400
Name all three types of waves and give an example of each.
Transverse: shaking a rope up and down,
Longitudinal: sound waves,
Surface: ocean waves
400
When the direction of a wave bends
refraction
400
Describe the wave using the words frequency and wavelength.
high frequency, short wavelength
400
DAILY DOUBLE!!!
Give an example as evidence that waves transfer energy.
Example: Sound waves can cause objects to vibrate
Earthquakes cause building to move/fall
Microwaves cause food to heat up
500
Name three criteria for waves
1. transfer energy
2. cause particles to move in repetitive patterns
3. travel through media
500
Some waves do not require a medium to travel through (such as light). What do we call those waves?
electromagnetic waves
500
Name and explain 3 things that are happening to sound when you scream in your room.
Reflection: the sound echos from your walls
Transmission: the sound travels through the wall, door, and windows
Absorption: the sound transfers energy to the objects in your room
500
What do you measure the frequency of a wave?
You count the number of crests that pass by in 1 second
500
Sound travels the fastest through solids, liquids, or gases? Why?
Solids, because the particles in solids are closely packed together, allowing them to bump into each other more quickly
