Characteristics of W
This is a study stack to help me learn characteristics of waves
Question | Answer |
---|---|
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 |
