Waves and sound Flashcards
What are waves?
Waves are transferring energy from 1place to another and the movement of particles
What are 2 types of waves?
Transversal and Longitudinal waves
In longitudinal waves , the vibrations are __________________.
Parallel to the direction of energy transfer of the waves
In transversal waves , the vibrations are ____________________.
Perpendicular to the direction of energy transfer of the waves
What are the movement of the particles?
Vibrations and oscillation
What do waves need to be formed ?
They need particles to be formed . They need a medium
What’s a trough?
The lowest point of transverse waves
What’s a crest/peak?
The highest point of transverse waves
What’s an amplitude?
The distance between the resting point and the peak / trough
What’s the wavelength?
The distance between 2 similar points
What does compression in a wave mean?
Particles are closer to each other
What does refraction in a wave mean?
Area of waves where the particle is
What does frequency in a wave mean?
Number of waves passing through a point in one second ( higher wave point = lower frequency)
Energy is transferred by ____ particles . Sound waves transfer _____ from source to detector through a ______ . Waves transfer energy without transferring ___ particles do not travel from the source to detector . The vibrating particles move ________ and ________.
Air , Energy , Medium , Air , Backwards , Forwards
Sound can travel at different ______ depending on the ______ it is travelling through , Sound travels faster in a _____ than it does in a ___ or ______ , This is because the particles in a solid are ______ than they are in a gas.
Speeds , Medium , Solid , Gas , Liquid , Closer
