Wave Properties
wave
A ____________ is the disturbance of matter that transfers energy through the medium from one point to another
medium
A _____________ is an environment through which the energy travels; state of matter: solid, liquid, or gas
False, a wave does NOT carry matter with it! It just moves the matter as it goes through it. Waves transfer energy, but do not transfer matter!
True or False? Waves move matter.
speed
What is the distance a wave travels in a given amount of time measured in meters per second (m/s)?
resting position
What is the equilibrium of a wave?
equilibrium/ resting position
What is the label for A?
Amplitude is directly related to the energy of a wave. The higher the amplitude, the greater the energy. If amplitude increases energy increases. The lower the amplitude, the less energy. If amplitude decreases energy decreases.
What is the relationship between the amplitude and energy of a wave?
The higher the frequency, the shorter the wavelength. The lower the frequency, the longer the wavelength.
What is the relationship between wavelength and frequency?
amplitude
What property of waves is the displacement (change in position) of particles in a wave from equilibrium?
crest
What would you label B?
trough
What would you label C?
amplitude?
What would you label D?
wavelength
What would you label E?
#1, the top wave since it has the greatest amplitude
Which wave #1-4 (top to bottom) has the most energy?
frequency
_______________ is the number of waves that pass a given point per second measured in hertz (HZ).
wavelength
_________________ is the distance between a point on one wave and the exact same point on the next wave. i.e. crest to crest and trough to trough
No. Changing the amplitude is independent from the wavelength & frequency.
Does a change in amplitude have an effect on wavelength or frequency?
bottom wave
Does the top or bottom wave have a longer wavelength?
distance between the equilibrium (resting position) and the crest or trough
How do we measure amplitude?
The wavelength is doubled. A decrease in frequency results in an increase in wavelength.
If the frequency is halved, what happens to the wavelength?
The frequency will be doubled. As wavelength decreases, frequency increases.
If the wavelength is halved, what happens to the frequency?
crest
What do you call the highest point on a wave (the top)?
trough
What do you call the lowest point on a wave (the bottom)?
