Idk What Chapter This Is Flashcards
Longitudinal Wave
Matter the medium moves back-and-forth along the same direction the wave travels
Wave
A repeating disturbance that transfers energy through matter or space
Medium
A matter through which a wave travels
Mechanical waves
Waves that can travel only through matter
Transverse waves
Particles in the medium, move back and forth at right angles to the direction that the waves travel
Crest
The High Point of a transverse wave
Trough
The low point of a transverse wave
Compression
The more dense region of a longitudinal wave
Rarefaction
The less dense region of a longitudinal wave
Wavelength
The distance between one point on a wave and the nearest point just like it
Frequency
The number of wavelengths that pass a fixed point each second
Amplitude
The measure of the size of the disturbance from a wave
Refraction
The bending of a wave caused by a change in its speed as it travels from one medium to another
Diffraction
The bending of a wave around an object
Interference
The process of two or more waves overlapping, and combining to form a new wave
Standing wave
A special type of wave pattern that forms when waves equal on wavelength and amplitude, travel in opposite directions, continuously interfere with each other
Nodes
Locations where the interfering waves always cancel
Resonance
The process by which an object is made to vibrate by absorbing energy at its natural frequencies
Period
The amount of time it takes one wavelength to pass a fixed point
Light is a type of () that can travel through empty space.
Wave
Ocean waves disturb the water and transfer () through it.
Energy
A wave will continue to travel as long as it has () to carry.
Energy
Anything that moves up and down and back and forth in a rhythmic way is a ().
Vibration
A drum, when it is stuck, makes a () wave.
Compressional
When a sound wave enters your ear, it causes your eardrum to ().
Vibrate
Frequency is expressed in ().
Hertz
The frequency of a wave is always equal to the () of the source that creates it.
Rate of vibration
Why do seismic waves spread out from the epicenters of earthquakes?
Compressional waves travel from the center outward; Dillution.
As the frequency of a wave increases, what happens to the period?
It decreases.
