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)?
