Wave motion
What are the two types of wave motion?
Transverse and Longitudinal
Sound waves require a ____________________ to travel.
Medium
Speed, amplitude, wavelength, frequency.
The amplitude of a wave describes its force or impact on another object. Amplitude of a sound wave is measured in ________________.
Decibles
What is the difference between longitudinal wave motion and transverse wave motion? (use the words energy and force)
Longitudinal = energy travels parallel to the force which caused the wave
Matter in any state (solid, liquid, gas) can be a medium for sound waves. In general sound waves will travel fastest through the ________________ state of matter.
Solid
Transverse waves have a p_____________ and a t______________.
peak, trough
If a transverse wave were graphed two dimensionally (x,y) the _______________ would be graphed using the x- axis and the _______________ would be graphed using the y-axis.
Wavelength, amplitude
What type of wave motion is associated with sound waves?
Longitudinal
Why does sound transmit fastest through solids?
Particles are closer together.
Longitudinal waves have a c________________ and a r__________________.
Compression, rarefaction
What type of wave motion is associated with light waves?
Transverse
How does temperature of a medium affect the speed of sound?
As the average kinetic energy of the medium increases the speed of sound increases. There is a positive relationship between temp of medium and speed of sound.
Describe wavelength.
Wavelength is the distance between one part of a wave and the next part just like it.
What are the types of wave motion is associated with light waves?
Transverse
Is the matter of a medium displaced as a sound wave travels through it?
No, the matter will move but is not displaced because it will return to its starting position.
Describe frequency.
The frequency of a wave is how many waves pass a given point in a second of time.
