# Characteristics of W

### This is a study stack to help me learn characteristics of waves

What is a wave? A wave is a disturbance that carries energy from place to place
What is a medium? A medium is the object through which a wave travels
How do waves transfer energy? When a wave travels under a floating object, the object moves up and down but doesn't travel with the wave
What causes waves? Waves are caused when a source of energy causes a medium to move
What two types of waves there are? Transverse waves and longitudinal waves
Transverse waves Transverse waves are waves that move the medium to the direction in which the waves travel
Longitudinal waves Longitudinal waves are waves that move the medium parallel to the direction the wave travels
What is amplitude? Amplitude is the maximum distance the wave travels
Amplitude of transverse waves Is the maximum distance the medium moves up and down from its resting position
Amplitude of longitudinal waves Is the maximum measure of how reversed the wave becomes
What is wavelength? Wavelength is the maximum distance the wave travels before it repeats
What is frequency? Wave frequency is the number of waves that pass the given point in a certain amount of time
What is speed? Wavelength*Frequency
What is Frequency? Speed/Wavelength
What is wavelength? Speed/Frequency
What is Reflection? Reflection is the interaction with the surface
What is Refraction? Refraction is the bending of waves due to change of speed
What is Diffraction? Diffraction is when a wave moves around a barrier or an opening barrier
What is Interference? Interference is the interaction of waves that meet
What 2 types of interference waves are there? Constructive wave and Destructive wave
What is a constructive wave? Constructive waves are waves with a larger amplitude
What is a destructive wave? Destructive waves are waves with smaller amplitude
What are Standing waves? Standing waves are waves that appear to be standing in one place
What is Resonance? Resonance is an increase in amplitude of a vibration
What are seismic waves? Seismic waves are waves caused by earthquakes
What 2 types of seismic waves are there? P waves and S waves
What are P waves? P waves are longitudinal seismic waves
What are S waves? S waves are transverse seismic waves
What are surface waves? Surface waves are waves that are combined with longitudinal waves and transfers waves
How to detect a seismic wave You use a seismograph. A seismograph records the ground
What carries waves Waves travel by medium
Mechanical waves Waves that require medium
Vibraton A repeated back-forth or up-down motion
crest and trough Crest the highest part of a transverse wave and trough the low part of the transverse wave

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
