Unit 5 Science Vocab Flashcards
What particles move perpendicular to the direction the waves travel
Transverse wave
Longitudinal wave
Particles that move back and forth in the same direction that the waves travel
A wave
A disturbance that transfers energy from one place to another
What is a measure of how far particles in the medium move away from its normal position
A amplitude
A medium
The material through which waves travel
Electromagnetic waves
Are disturbances in electric and magnetic fields
What is the time required for one cycle called
Wave period
What particles move back and forth in the same direction that the wave travels
Longitudinal wave
What waves require a medium
Mechanical waves
What is the material through which a wave travels
A medium
A amplitude
A measure of how far particles I The median move Away from its normal rest position
What is the disturbance that transfers energy from one place to another
A wave
What is the speed at which wave travels
Wave speed
a wavelength
Is the distance over which the waves shape repeats
What does frequency do
Tells you how many cycles occur in an amount of time
What is hertz
it’s what frequency is usually measured in
What ripples on a waters surface and expands out
Waterfronts

It’s the time required for one cycle
What is the transfer of energy as EM waves
Radiation
What is a wave front
It’s when ripples on a water surface expand in two dimensions
