100
the top point of a wave
What is a crest?
100
the amplitude of this wave
What is 3?
100
Which property of a sound wave tells you how loud it is?
amplitude
100
Is this wave transverse or longitudinal?
What is longitudinal?
100
True or false: Pitch of a sound wave depends on the frequency of the wave
What is true?
200
the point where a wave crosses the resting line
What is a node?
200
the wavelength of this wave
What is 4?
200
Is sound a transverse or longitudinal wave?
What is longitudinal
200
All of the troughs in this image
What are D and H
200
The type of wave that needs a medium to travel
Longitudinal (compression) waves such as sound waves or seismic waves
300
Is this wave transverse or longitudinal?
What is transverse?
300
the frequency of this wave (the image is 1 second of the wave)
What is 4 Hz?
300
the reason a sound wave can't travel through outer space
it is a mechanical wave/ it needs a medium
300
Frequency of this wave (it happens in 1 second
5 Hertz
300
What is a medium?
the material a wave travels through
400
the distance from one point on a wave to the same point on the next wave (example: distance from crest to crest)
What is wavelength?
400
Where you measure amplitude of a wave
What is the crest to the resting line OR the trough to the resting line
400
Do high or low pitched sounds have more energy? Why?
High pitched because they have a higher frequency
400
Which wave has a higher pitch AND WHY?
Sound A because it has a higher frequency
400
What happens to wavelength of the wave when frequency gets higher?
The wavelength decreases/gets shorter
500
a wave where the particles of the wave move parallel to the direction of the wave
What is a longitudinal wave?
500
What unit do you use to measure frequency?
A. centimeters
B. Hertz
C. square feet
B
500
Wave 1 has a higher amplitude. Wave 2 has a greater wavelength. Which wave is louder?
A. Wave 1
B. Wave 2
C. Not enough information
A. Wave 1
500
Which of these sound waves has the highest pitch? (challenge)
C
500
What 2 properties of a wave show how much energy it has?
(high) amplitude and (high) frequency
