Mechanical Waves
What is Compression?
This property of a wave is the number of times a wave passes in a given amount of time.
What is frequency?
An electromagnetic wave involves the transfer of these types of energy.
What is electric and magnetic energy.
This is why you see lightning before you hear thunder.
Because light waves travels faster than sound waves.
The more of this a mechanical wave has, the greater its amplitude is.
What is energy?
The high point on a transverse wave is called this.
What is a crest?
The distance between two corresponding parts of a wave is the wave's what.
What is wavelength?
Unlike other waves, electromagnetic waves don't need this to transfer energy.
What is a medium.
In a coiled spring, the areas where the coils are furthest apart are called this.
What is rarefaction.
Mechanical waves are classified according to this
How they move
Sound waves are these kind of waves
What is longitudinal?
Frequency is measured in these units
What are hertz?
This type of light consists of waves that vibrate in only one direction.
What is polarized light.
In a transverse wave, the particles move this way to the direction in which the way the wave is traveling.
What is at right angles (up and down).
Mechanical waves are created when a source of energy causes a medium to do this.
What is vibrate.
Waves that move the particles of the medium parallel to the direction in which the waves are traveling are called this.
What are longitudinal waves.
To get the speed of a wave, you must do this.
Multiply the frequency and it's wavelength.
In a phenomenon known as this, electric current will flow when light shines on certain substances.
What is photoelectric
The crests and troughs of a standing wave are called this.
What are aninodes
These waves combine both properties of longitudinal and transverse waves so that the particles in the wave with a circular motion.
What are surface waves.
In a transverse wave, in what direction does the medium move relative to the direction of the wave.
As the energy moves up and down (vertically), the wave moves horizontally.
As the frequency of a wave traveling at constant speed increases, this decreases.
What is its wavelength?
In the electromagnetic wave model, these travel up and down (vertical) and these travel side to side (horizontally)
Waves combine to produce a smaller or zero-amplitude wave in a process called this
What is destructive interference.
